Copper-Catalyzed C(sp(3))-H/C(sp(3))-H Cross-Dehydrogenative Coupling with Internal Oxidants: Synthesis of 2-Trifluoromethyl-Substituted Dihydropyrrol-2-ols

The first oxidative C(sp(3))-H/C(sp(3))-H cross-dehydrogenative coupling (CDC) reaction promoted by an internal oxidant is reported. This copper-catalyzed CDC reaction of oxime acetates and trifluoromethyl ketones provides a simple and efficient approach towards 2-trifluoromethyldihydropyrrol-2-ol derivatives in a highly diastereoselective manner by cascade C(sp(3))-C(sp(3)) bond formation and cyclization. These products were further transformed into various significant and useful trifluoromethylated heterocyclic compounds, such as trifluoromethylated furan, thiophene, pyrrole, dihydropyridazine, and pyridazine derivatives. A trifluoromethylated analogue of an A beta(42) lowering agent was also synthesized smoothly. Preliminary mechanistic studies indicated that this reaction involves a copper(I)/copper(III) catalytic cycle with the oxime acetate acting as an internal oxidant.

Application of 1799-84-4, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 1799-84-4 is helpful to your research.

Red Light-Emitting Electrochemical Cells Employing Pyridazine-Bridged Cationic Diiridium Complexes

A rigid dinuclear Ir(III) complex showing high photoluminescence quantum yield in pure films was successfully used to fabricate light-emitting electrochemical cells with and without ionic liquid additives. The devices showed nearly instantaneous electroluminescence after biasing and maximum quantum yield approaching 1%. The lifetime of the devices was found to be limited to approximately 20 hours, which we correlated with the irreversible oxidation of the complex as seen from electrochemical measurements. This work validates the use of highly luminescent dinuclear iridium complexes in light-emitting electrochemical cells. Future studies will pursue materials with more efficient photoluminescence as well as improved electrochemical stability. (c) 2019 The Electrochemical Society.

The four new compounds were characterized by elemental analysis, IR spectroscopy and H-1/C-13 NMR and the crystal structures of 1-3 were solved by single crystal X-ray diffraction to elucidate their molecular structure. In the light of their structural knowledge, an analysis of the role of the substituent and steric effects on the crystal packing is carried out. Focusing on their dppn fragment of 1-3, an approximate s-trans/s-trans-conformation of the rings occurs as in the free dppn molecule and the bond lengths and angles agree with those reported for this molecule. pi-pi interactions and hydrogen bonds involving the substituents occur in 1 and 2. In addition, the water molecule of crystallization in 3 plays an important role in determining the crystal packing. (C) 2020 Elsevier B.V. All rights reserved.

Comprehension of the Effect of a Hydroxyl Group in Ancillary Ligand on Phosphorescent Property for Heteroleptic Ir(III) Complexes: A Computational Study Using Quantitative Prediction

A new Ir(III) complex (dfpypya)(2)Ir(pic-OH) (2) is theoretically designed by introduction of a simple hydroxyl group into the ancillary ligand on the basis of (dfpypya)(2)Ir(pic) (1) with the aim to get the high efficiency and stable blue-emitting phosphors, where dfpypya is 3-methyl-6-(2′,4′-difluoro-pyridinato)pyridazine, pic is picolinate, and pic OH is 3-hydroxypicolinic acid. The other configuration (dfpypya)(2)Ir(pic OH)’ (3) is also investigated to compare with 2. The difference between 2 and 3 is whether the intramolecular hydrogen bond is formed in the (dfpypya)(2)Ir(pic OH). The quantum yield is determined by three different methods including the semiquantitative and quantitative methods. To quantitatively determine the quantum yield is still not an easy task to be completed. This work would provide some useful advices to select the suitable method to reliably evaluate the quantum yield. Complex 2 has larger quantum yield and more stability as compared with 1 and 3. The formation of intramolecular hydrogen bond would become a new method to design new phosphor with the desired properties.

Covalent Post-assembly Modification Triggers Structural Transformations of Borromean Rings

A series of supramolecular transformation cascades are presented here, employing ligand exchange reactions, concentration-dependent Borromean ring (BR) linking and unlinking, and inverse electron-demand Diels Alder (IEDDA) reactions. The new family of template-free, tetrazine-edged BRs are constructed by using ligand exchange reactions, and their concentration dependent linking and unlinking reactions have been observed. Moreover, Borromean precursors have been demonstrated to further undergo supramolecular structural transformations induced by rapid and efficient IEDDA reactions to afford corresponding post-assembly modified architectures. Remarkably, subtle steric increases of the pyridazine fragments obtained by IEDDA reactions is regarded to induce controlled topological transformations in the cascade, unlinking the Borromean structures by using electron-rich dienophiles as triggering signals.

Crystal structures of eight 3D molecular adducts derived from bis-imidazole, bis(benzimidazole), and organic acids

Cocrystallization of the bis(imidazole)/bis(benzimidazole) with a series of organic acids gave a total of eight molecular adducts with the compositions: (3,6-bis(imidazole-1-yl)pyridazine): (trichloroacetic acid)(2) (1) [(H(2)L1)(2+) center dot (tca(-))(2), L1 = 3,6-bis(imidazole-1-yl)pyridazine, tca(-) = trichloroacetate], (bis(N-imidazolyl)methane): (suberic acid) (2) [(L2) center dot (H(2)suba), L2 = bis(N-imidazolyl)methane, H(2)suba = suberic acid], bis(N-imidazolyl)methane: (3-nitrophthalic acid): 3H(2)O (3) [(H(2)L2)(2+) center dot (3-Hnpa(-))(2) center dot 3H(2)O, 3-Hnpa(-) = 3-nitro hydrogenphthalate], (bis(N-imidazolyl)butane)(0.5): (4-nitrophthalic acid): H2O (4) [(H(2)L3)(0.5)(+) center dot (4-Hnpa(-))(-) center dot (HO)-O-2, L3 = bis(N-imidazolyl)butane, 4-Hnpa(-) = 4-nitro hydrogenphthalate], (1(3-(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole): (3,5-dinitrosalicylic acid) (5) [(HLA) center dot (3,5-dns(-)), L4 = 1-(3-(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole, 3,5-dns(-) = 3,5-dinitrosalicylate], (1-(3(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole): (3-nitrophthalic acid) (6) [(H(2)L4) center dot (3-npa(2-)), L4 = 1(3-(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole, 3-npa(2-)=3-nitrogenphthalate], (bis(N-imidazolyl) butane): (pamoic acid) (7) [(H(2)L3) center dot (pam), pam = pamoate], and (3,6-bis(imidazole-1-yl)pyridazine): (1,5-naphthalenedisulfonic acid) [(H(2)L1)(2+) center dot (nPda)(2-) = 1,5-naphthalenedisulfonate] (8). The eight adducts have been characterized by X-ray diffraction technique, infrared spectrum, and elemental analysis, and the melting points of all adducts were also reported. And their structural and supramolecular aspects are fully analyzed. The result reveals that among the eight investigated crystals both the end ring N in the bis(imidazole) moieties are protonated when the organic acids are deprotonated except 2, and 5, and the crystal packing is interpreted in terms of the strong ionic N-H center dot center dot center dot O H-bond between the imidazolium and the deprotonated acidic groups. Except the N-H center dot center dot center dot N H-bond, the O-H center dot center dot center dot O H-bonds were also found at the salts 3, 4, 5, and 7, salt 5 has the additional N-H center dot center dot center dot N H-bond, the N-H center dot center dot center dot S H-bond was established at 8. Further analysis of the crystal packing of the adducts indicated that a different set of additional CH-O/CH2-O, CH-Cl, CH-pi/CH2-pi, Cl-C, CI-N, O-O, O-pi, OH-pi, and pi-pi associations contribute to the stabilization and expansion of the total 3D frameworks. For the coexistence of the various weak interactions these structures had homo or hetero supramolecular synthons or both. Some supramolecular synthons, such as R-1(2)(4),R-2(2)(7), and R-2(2)(8) usually found in crystals of organic acids with imidazole unit, were again shown to be appeared in constructing most of these H-bond networks.

Antimicrobial Pyridazines: Synthesis, Characterization, Cytotoxicity, Substrate Promiscuity, and Molecular Docking

A facile and convenient synthesis of new pyridazines suitable for use as antimicrobial agents was reported. The hydrazide intermediate was coupled with various benzaldehydes and/or acetophenones and cyclized instantaneously to afford target pyridazine derivatives. The structures of new pyridazines were confirmed by IR, H-1- and C-13-NMR, elemental analysis in addition to representative LC/MS. Antimicrobial activity was screened against 10 bacterial and fungal strains. The new pyridazines showed strong to very strong antibacterial activity against Gram-negative (GNB) bacteria, while none of them showed significant antifungal activity at the same concentration range. Chloro derivatives exhibited the highest antibacterial activity with MICs (0.892-3.744 mu g/mL) lower than that of chloramphenicol (2.019-8.078 mu g/mL) against E. coli, P. aeruginosa, and S. marcescens. Prediction of ADME parameters, pharmacokinetics, and substrate promiscuity revealed that these new pyridazines could be promising drug candidates. Cytotoxic studies on rat hepatocytes showed how much safe these new pyridazines on living organisms (IC50>64 mu g/mL). MOE docking studies showed a good overlay of these new pyridazines with co-crystallized ligand within an E. coli DNA gyrase subunit B active sites (4KFG).

Direct C-H photoarylation of diazines using aryldiazonium salts and visible-light

In this study, direct C-H photoarylation of pyrazine with aryldiazonium salts under visible-light irradiation (blue-LEDs) is described, and additional examples including photoarylations of pyrimidine and pyridazine are also covered. The corresponding aryl-diazines were prepared in yields up to 84% only by mixing and irradiating the reaction with no need for an additional photocatalyst. We demonstrate the efficacy of this protocol by the scope with electron-donor, -neutral, and -withdrawing groups attached at theortho,meta, andparapositions of the aryldiazonium salts; the results are better than those reported for ruthenium-complex mediated photoarylations. Additionally, we demonstrate the robustness of this methodology with a 5 mmol scaled-up experiment. Mechanistic studies were carried out giving support to the proposal of a photocatalyzed approach by an electron donor-acceptor (EDA) complex, also highlighting the crucial role that solvents play in the formation of the EDA complex.

Comparison of structural, spectroscopic, theoretical and thermal properties of metal complexes (Zn(II), Mn(II), Cu(II), Ni(II) and Co(II)) of pyridazine-3-carboxylic acid and pyridazine-4-carboxylic acids

In our present work, we studied complexes of 3d-transition metals with pyridazine-3-carboxylic and pyridazine-4-carboxylic acids. The synthesis of manganese(II), cobalt(II), nickel(II), copper(II) and zinc(II) complexes with pyridazinecarboxylic acids was performed. The effect of selected 3d-transition metal ions on the electronic system of ligands and the thermal properties of the complexes by the use of TG-FTIR were studied. The products of dehydration and decomposition processes of studied compounds were determined from the TG (thermo-gravimetric) and DSC (differential scanning calorimetry) curves. The crystal structures of manganese(II) pyr-idazine-3-carboxylate acid and pyridazine-4-carboxylate were analysed by the use of single-crystal X-ray ana-lysis. The geometries, NBO atomic charges, energy of HOMO and LUMO orbitals were calculated in the B3LYP/6-311++G(d,p) level. The aromaticity of ligands and complexes were discussed on the basis of HOMA and Bird’s indices. The influence of the type of metal ion coordination and the location of the carboxylate anion in the pyridazine ring on the aromaticity of complexes were discussed. The comparison of the effect of metal ions on the electronic charge distribution and aromaticity of pyridazynecarboxylic and pyridinecarboxylic acids (i.e. nicotinic and picolinic acids) was done.

One-Pot, Telescopic Approach for the Chemoselective Synthesis of Substituted Benzo[e]pyrido/pyrazino/ pyridazino[1,2-b][1,2,4]thiadiazine dioxides and Their Significance in Biological Systems

The one-pot telescopic approach has been developed for the chemoselective synthesis of substituted benzo[e]pyrido/pyrazino/pyridazino[1,2-b][1,2,4]thiadiazine dioxides using readily available 2-aminopyridines/pyrazines/pyridazine and 2-chloro benzene sulfonyl chloride. This one-pot procedure involves the chemoselective sulfonylation of 2-aminopyridines/pyrazines/pyridazine with 2-chloro benzene sulfonyl chloride followed by a Cu(I)-catalyzed Ullmann-type C-N coupling reaction to obtain benzo[e]pyrido/pyrazino/pyridazino[1,2-b][1,2,4]thiadiazine dioxides with broad substrate scope and high functional group tolerance. The synthetic sequence merges well with the nucleophilic attack on the 2-amino group of pyridines/pyrazines/pyridazines on the 2-chloro benzene sulfonyl chloride, followed by Cu(I)-catalyzed ipso chloro displacement to C-N bond formation resulting in a more modular and straightforward approach. Moreover, the biological significance of the synthesized benzothiadiazine dioxides was evaluated by following their ability to bind to protein macromolecules and their anti-inflammatory activity.
