Alkylation of 5-aryl(hetaryl)tetrazoles with methyl chloromethyl ether under conditions of phase-transfer catalysis leads to formation of isomeric 1- and 2-methoxymethyltetrazoles at a ratio of similar to1:2. The reaction of 5-substituted tetrazoles with alpha-methylstyrene in the presence of trichloroacetic acid gives the corresponding 2-(alpha,alpha-dimethylbenzyl)tetrazoles in high yield and with high regioselectivity.
