Equilibrium CH acidity of acetylenic derivatives of N-alkylazoles in DMSO

AbstractThe equilibrium CH acidity of a group of ethynylazoles in DMSO was measured by an intermetallization method. The dependence of the acidity of these compounds on the structure of the heterocycle, position of the ethynyl group, and nature of the substituents has been examined.

Synthesis and physicochemical investigation of mixed alkali-metal cation hexafluorosilicates

AbstractThe title compounds of MMSiF6 (M, M=Li, Na, K, Rb, Cs) and Li0.5Na1.5SiF6 composition have been synthesized. Their crystallographic, x-ray, and IR spectral properties were studied. The greatest distortion of the C3v symmetry of the hexafluorosilicate ion was observed in Li0.5Na1.
