Bu4NI catalyzes regioselective N2-alkylations and N2-arylations of tetrazoles using tert-butyl hydroperoxide as a methyl source, alkyl diacyl peroxides as primary alkyl source, alkyl peresters as secondary and tertiary alkyl sources, and aryl diacyl peroxides as arylating source. These reactions proceed without pre-functionalization of the tetrazoles and in the absence of any metal catalysts.
