Aleshunin, P. A. published the artcileVinyltetrazoles: II. Synthesis of 5-substituted 1(2)-vinyltetrazoles, Product Details of C8H5F3N4, the publication is Russian Journal of Organic Chemistry (2011), 47(12), 1882-1888, database is CAplus.
5-Substituted 1(2)-vinyltetrazoles (R = aryl, alkyl, vinyl, NH2, H) were synthesized by alkylation of appropriate tetrazoles with Br(CH2)2Br in the presence of Et3N in MeCN, followed by elimination of Et3N.HBr. 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 N(1),N(2′)- and N(2),N(2′)-divinyl derivatives
