[1,2,5]Oxadiazolo[3,4-d]pyridazine 1,5,6-trioxides: efficient synthesis via the reaction of 3,4-bis(hydroxyimino)methyl)-1,2,5-oxadiazole 2-oxides with a mixture of concentrated nitric and trifluoroacetic acids and structural characterization

An efficient synthesis of [1,2,5]oxadiazolo[3,4-d]pyridazine 1,5,6-trioxides (1) from 3,4-bis(hydroxyimino)methyl)-1,2,5-oxadiazole 2-oxides using a mixture of concentrated nitric and trifluoroacetic acids has been developed. The scope of the unconventional reaction was established. The 4,7-dinitro[1,2,51 oxadiazolo[3,4-d]pyridazine 1,5,6-trioxide if represents a new high energy compound, unfortunately with low thermal stability. The parent [1,2,5]oxadiazolo[3,4-d]pyridazine 1,5,6-trioxide lc was studied by single-crystal X-ray diffraction analysis which revealed a planar molecule with an unusually long intracyclic N-N bond of 1.668(5) angstrom and unexpected exo-cyclic bond angles at the nitroxyl nitrogen atoms. In the crystal, the molecules of Ic are bound to each other by strong pi-pi stacking and C-H center dot center dot center dot O hydrogen bonding interactions into a three-dimensional framework that results in a high crystal density of 1.833 gcm(-3).

Adsorption and inhibition effect of 2,4-diamino-6-hydroxypyrimidine for mild steel corrosion in HCl medium: experimental and theoretical investigation

2,4-Diamino-6-hydroxypyrimidine (2D6H) was examined as corrosion inhibitor of mild steel (MS) in 0.1M HCl using potentiodynamic measurements, linear polarization resistance (LPR), scanning electron microscopy, electrochemical experiments, and quantum chemical calculations. All measurements show that the corrosion inhibition effectiveness is forthright compared to the concentration of 2D6H ranging from 0.5 to 10.0mM. Adsorption of 2D6H on the MS surface in the presence of HCl is determined to obey Langmuir adsorption isotherm. The electronic features elucidated by quantum chemical calculations were associated with the experimental inhibition productivities. The mechanism of inhibition was revealed by E-pzc measurements.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 110-03-2. Quality Control of 2,5-Dimethyl-2,5-hexanediol.

Substituent effects at nitrogen/phosphorus atoms of dialkaline earth metal complexes: Excess electron and large second-hyperpolarizability

A number of imido-, amido-, and phosphido-bridged dialkaline earth metal (M = Be, Mg, and Ca) complexes and their alkali metal (Li and Na) derivatives have been considered to study the ground state structure and the second-hyperpolarizability. The calculated ground state geometries contain four-membered M-N(P)-M-N(P) ring having either planar or butterfly-like bent structure. The second-hyperpolarizability has been calculated at the HF and CCSD(T) levels using Sadlej’s pol and aug-pc-2 basis sets, respectively. The addition of second hydrogen/alkali metal atom on nitrogen/phosphorus (N/P) atom substantially reduces the charge transfer from the alkaline earth metal atoms as the high negative charge on N/P exerts stronger push effect on the outermost electron pair in the ns sub-shell of M. The excess electron density on the alkaline earth metal atoms plays a crucial role in the enhancement of second-hyperpolarizability. The sum-over-state method calculated two-photon contribution of second-hyperpolarizability has been found to be significant. The variation of second-hyperpolarizability has been explained satisfactorily in terms of the TD-CAMB3LYP calculated spectroscopic properties in the light of two-state model. The calculated mean second-hyperpolarizabilities of alkali substituted amido- and phosphido-bridged complexes are in the order of 10(7) au.

The present article describes the synthesis, characterization, and antidiabetic activity of 6-methoxyimidazo[1,2-b]pyridazine derivatives 7a-l. The synthetic sequence for the preparation of these derivatives involves the following prominent reactions: (a) Step 1: involves the high-pressure amination reaction; (b) Step 2: involves the Zinc oxide nanoparticle-catalyzed cyclization reaction; (c) Step 3: involves the methoxylation; (d) Step 4: involves the bromination reaction; (e) Step 5: involves the Suzuki coupling reaction; (f) Step 6: involves the reduction of the -NO2 group; (g) Step 7: involves Boc protection of the 1(o) amino group (h) Step 8: involves diazotization of the amine group and finally the last of the synthesis (i) Step 9: involves the saponification of the ethyl ester group. Furthermore, the structures of the newly synthesized 6-methoxyimidazo[1,2-b]pyridazine derivatives 7a-l were determined using H-1 NMR, C-13 NMR, and Mass and IR spectroscopic analyses. These derivatives were evaluated for their antidiabetic property and the results revealed that most of the compounds exhibited significant potency. It is worth mentioning that compounds 7b (69.87%), 7f (69.0%), 7h (68.79%), and 7l (68.61%) with substitution R = para-NH2, para-COOH, meta-NH2, and meta-COOH, respectively, showed significant (good) hypoglycemic activity when compared to the standard drug insulin (50 mg/kg b.w) in reducing the blood glucose level.

Why lithiation results large enhancement of second hyperpolarizability of delta shaped complexes M-C2H2 (M = Be, Mg and Ca)?

Lithiation of M-C2H2 results significant enhancement of second-hyperpolarizability. The negatively polarized pi-surface of C2Li2 raises the molecular orbital energies which strongly favours both metal-HOMO to ligand-LUMO and ligand-HOMO to metal-LUMO charge transfer interactions. Due to the push electron effect by C2Li2 , the outermost ‘ns’ orbital of alkaline earth metal cannot induce charge transfer instead forms the excess diffuse electron density localized over the alkaline earth metal. Calculated vertical ionization energy of M-C2Li2 complexes are smaller than the corresponding isolated metals. CCSD calculated static and dynamic second-hyperpolarizabilities of M-C2Li2 complexes are many times larger than that of the corresponding M-C2H2 complexes.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5469-69-2, you can contact me at any time and look forward to more communication. SDS of cas: 5469-69-2.

Reactions of the Schiff base ligand derived from 4-acetyl-5,6-diphenyl-3(2H)-pyridazinone and ethyl-enediamine with Ni(II) and Co(II) using different metal salts; NO3, AcO, ClO4 and Cl yielded binary metal complexes. Mixed-ligand complexes were synthesized by using extra ligands including 8-hydroxyquinoline or glycine as nitrogen, oxygen-donors; 1,10-phenanthroline or 2-aminopyridine as nitrogen, nitrogen-donors. Elemental and thermal analyses, spectroscopic techniques (IR, electronic and mass), conductivity and magnetic susceptibility measurements were utilized to characterize the structures of the complexes. Electronic spectra and magnetic moment measurements showed that all complexes are octahedral and tetrahedral. In addition, activation energies of thermal degradation were calculated by means of Coats-Redfern equations. The activation energies were also used to evaluate kinetic and thermodynamic parameter of the metal complexes including Ea, Delta H, Delta S and Delta G. The XRD patterns for the ligand and its metal complexes indicate crystalline nature with nano particle sizes. The biological activity of the chelating agent and its metal complexes was conducted towards S. aureus and B. subtilis as Gram-+ve bacteria, S. typhimurium and E. coli as Grame-ve bacteria, C. albicans (yeast) and A. fumigatus (fungus). The chelating agent and some Ni(II) and Co(II) complexes showed antitumor activity towards HepG2 cell line. (C) 2020 Elsevier B.V. All rights reserved.
