Abstract

Abstract 5-R-Substituted 1 (2)-vinyltetrazoles (R= Ar, Alk, CH 2= CH, NH 2, 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 (1 H-tetrazol-5-yl)-methane and 1, 3-bis (1 H- tetrazol-5-yl) benzene, under analogous conditions gave the corresponding N 1, N 2′- ...
