Static second hyperpolarizability of inverse sandwich compounds (M-1-C5H5-M-2) of alkali (M-1 = Li, Na, K) and alkaline earth metals (M-2 = Be, Mg, Ca)

In the investigated inverse sandwich complexes, charge transfer from alkali metal (M1) led to aromatically stabilized Cp ring, which prevented further charge transfer from the alkaline earth metal (M2). This electron push effect resulted in diffusion of electron density from the outermost ns” subshell of alkaline earth metal. The alkaline earth metal is weakly bound to the alkali metal-C5H5 complex. The vertical ionization energy of the chosen M1-Cp-M2 complexes was smaller than that of the corresponding alkaline earth metals. Large second hyperpolarizability (106-108 a. u.) was obtained for the studied molecules. The correction due to the basis set superposition error (BSSE) in the calculated second hyperpolarizability was found to be small for larger systems, while it was rather significant for small systems. The MP4SDQ and CCSD results were in fair agreement, which indicates the necessity of higher order electron correlation treatment in the accurate description of second hyperpolarizability. Calculated dynamic second hyperpolarizabilities at 1064 nm were found to increase considerably for most of the chosen metal complexes.

Convenient synthetic path to ethyl 1-aryl-5-formyl-1H-1,2,3-triazole-4-carboxylates and 1-aryl-1,5-dihydro-4H-[1,2,3]triazolo[4,5-d]pyridazin-4-ones

A convenient method for selective synthesis of ethyl 1-aryl-5-formyl-1H-1,2,3-triazole-4-carboxylates and 1-aryl-1,5-dihydro-4H-[1,2,3]-triazolo[-4,5-d] pyridazin-4-ones has been developed. New ethyl 1-aryl-5-(diethoxymethyl)-1H-1,2,3-triazole-4-carboxylates were prepared by the reaction of different aryl azides and ethyl 4,4-diethoxy-3-oxobutanoate and readily converted into ethyl 1-aryl-5-formyl-1H-1,2,3-triazole-4-carboxylates in high overall yields. Such aldehydes were found to be reactive in several condensation reactions. Reaction of ethyl 1-aryl-5-formyl-1H-1,2,3-triazole-4-carboxylates and hydrazine provided 1-aryl-1,5-dihydro-4H-[1,2,3] triazolo[4,5-d]pyridazin-4-ones in excellent yields.

Dodecanoyl isothiocyanate and N ‘-(2-cyanoacetyl) dodecanehydrazide as precursors for the synthesis of different heterocyclic compounds with interesting antioxidant and antitumor activity

Dodecanoyl isothiocyanate 1 was utilized for the construction of thioureido, 2-thioxo-2,3-dihydroquinazolin-4(1H)-one, benzo[d]-1,3-thiazin-4(H)-one and 3-amino quinazolin-4(3H)-one derivatives 2, 3, 4, and 5 respectively. However, N-(2-cyanoacetyl) dodecanehydrazide 6 was also used as a key starting material for the construction of a variety of new pyrazolone, pyrazole, thiadiazole, pyridazine, chromeno[2,3-c]pyrazole, and dithiolane derivatives 7, 9, 12, 15, 18, and 20, respectively. The newly synthesized compounds were characterized by elemental analyses and spectral data (IR, H-1 NMR, and mass spectra). Some of the newly synthesized compounds bearing heterocyclic moieties were tested for antioxidant activity as reflected in their ability to inhibit oxidation in rat brain and kidney homogenates using 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) inhibition. Also, in vitro anticancer activity was examined using the standard (3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide) (MTT) method against a panel of two human tumor cell lines namely; hepatocellular carcinoma HepG2 and mammary gland breast cancer MCF-7. Compounds 12 and 16b exhibited the highest activities as antioxidant and antitumor agents. Meanwhile, compounds 7 and 20 showed moderate activities and the rest of the tested compounds showed weak activities. [GRAPHICS] .

Click Chemistry Derived Pyridazines: Electron-Deficient Building Blocks with Defined Conformation and Packing Structure

A series of 3,6-bis(4-triazolyl)pyridazines equipped with terminal phenyl substituents with varying degree of fluorination were synthesized by using the facile copper-catalyzed azide-alkyne cycloaddition and their structures were thoroughly investigated in the gas phase, in solution, and in the solid state by employing DFT calculations, NMR spectroscopy, and single-crystal X-ray diffraction, respectively. On the molecular level, their structure is governed by the strong preference of the triazole-pyridazine linkages for the anti-conformation. The supramolecular organization of the molecules in the crystalline solid is controlled by -stacking, C-H as well as C-FH interactions. The latter can conveniently be tuned by the number and position of fluorine substituents in the terminal phenyl units, giving rise to either herringbone-like, 1D or 2D lamellar packing. Electrochemistry and optical spectroscopy of all compounds suggest that they might find use as electron-transporting/hole-blocking materials in organic electronics.
