New Schiff bases of 1-vinyl- and 1-ethyl-substituted imidazoles and benzimidazoles were synthesized. The condensation reactions of 2-amino- and 2-formylimidazoles with 2-aminobenzimidazoles are virtually independent of the nature of the substituent (

It was found that vinylpyrazoles react with thiols both according to ionic and according to free-radical mechanisms, with the formation of products of α- and β-addition. Radical thiylation of 1-vinylpyrazoles is a convenient method of synthesis of

The crystal and molecular structures of 1,1′-divinyl-2,2′-biimidazolyl (L) were determined by x-ray crystallographic analysis. It was established that the molecule of L has crystallographic symmetry 2 and a cisoid conformation with an angle of ro

In 1-viny1–2,2′-pyridylbenzimidazole, a double intramolecular specific C-H...N interaction is accomplished between the α-H of the vinyl group with the pyridine ring nitrogen and between the H3′ atom of the pyridine ring and the benzimidazole r

The factors that affect the chemical shifts in the 15N NMR spectra of N-vinylazoles were investigated. It was shown that an additional positive contribution to the shielding constant of the “pyridine” nitrogen atom occurs in the s-cis-(N(2)) conf

The specific intramolecular interaction between the α-proton of the vinyl group and the pyridine nitrogen atom of the second imidazole ring, similar to the hydrogen bond, is accomplished in 1-vinyl- and 1,1′-divinyl-2,2′-biimidazolyls. In 1-viny
