A Paterson olefination reaction involving 1-trimethylsilanylmethyl-1H-benzotriazole and either adamantanone or acetone, in the presence of n-butyllithium, is used to prepare 1-adamantylidenemethyl-1H-benzotriazole and 1-(2-methylpropenyl)-1H-benzotriazole respectively.Further treatment of these compounds with n-butllithium and an electrophile affords a variety of 1-heterosubstituted 1-(1-alkenyl)benzotriazoles.Photolysis of the latter compounds yields products from three competing pathways: cyclisation with C-C bond formation, cyclisation with C-S bond formation and halogen atom transfer.
