<Emphasis Type="Italic">N</Emphasis>-(2-chloro-1,2-difluorovinyl) derivatives of azoles

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 nucleophiles were examined.
