Abstract

The reaction of 5-(2-arylethenyl)-2-methyl-2H-tetrazoles with arenes (benzene, xylenes, tert-butylbenzene, anisole, veratrole, 1,2-dichlorobenzene) under conditions of superelectrophilic activation under the action of Brønsted superacids (CF3SO3H, FSO3H) or strong Lewis acids (AlCl3, AlBr3) leads regioselectively to the products of hydroarylation of the carbon–carbon double bond, viz., 5-(2,2-diarylethenyl)-2-methyl-2H-tetazoles, in yields of up to 95%.
