摘要: 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 triethylamine acetonitrile, followed elimination hydrobromide. Vinylation dinuclear substrates, such as bis(1H-tetrazol-5-yl)-methane and 1,3-bis(1H-tetrazol-5-yl)benzene, under analogous conditions gave corresponding N 1,N 2′- 2,N 2′-divinyl derivatives.
