5-R-Substituted 1(2)-vinyltetrazoles (R = Ar, Alk, CH₂=CH, NH₂, H) were synthesized by alkylation of 5-R-tetrazoles with 1,2-dibromoethane in the presence of triethylamine in acetonitrile, followed by elimination of triethylamine hydrobromide. Vinylation of dinuclear substrates, such as bis(1H-tetrazol-5-yl)-methane and 1,3-bis(1H-tetrazol-5-yl)benzene, under analogous conditions gave the corresponding N¹,N ^2′- and N²,N^2′-divinyl derivatives.
