Chemical properties of carbenes derived from 1-methyl-3-polyfluoroalkylimidazolium salts were studied. These unstable intermediate products reacted with carbon disulfide to give the corresponding imidazolium-2-carbodithioates which were subjected to methylation at the sulfur atom.

A facile synthetic route to N-polyfluoro(trimethylsilyl)ethyl azole derivatives was developed starting from N-bromo(chloro)polyfluoroethyl-substituted azoles. The silanes thus obtained were reacted with various electrophiles in the presence of the fluoride ion to yield the corresponding fluorinated carbinols, ketones, carboxylic acids, and methyl dithiocarboxylates as well as N-pentafluoroethylbenzimidazole

Reactions of N-(2,2-dichloro-1,1,2-trifluoroethyl)-substituted azoles with zinc, magnesium, butyllithium, and tris(diethylamino)phosphine were studied, and optimal conditions for the preparation of the corresponding N-(2-chloro-1,2-difluorovinyl) derivatives were found [tris(diethylamino)phosphine, chlorotrimethylsilane]. Some reactions of the obtained unsaturated fluorinated compounds with sulfur-centered
