Alkylation of 5-aryltetrazoles and 1-substituted tetrazole-5-thiones with 1,3-dibromo-2,2-bis(bromomethyl)propane in dimethylformamide in the presence of sodium hydroxide leads to the formation of tetrakis(5-aryltetrazol-2-ylmethyl)methanes and tetrakis(1-R-tetrazol-5-ylsulfanylmethyl) methanes, respectively. Microwave activation considerably shortens the reaction time and increases the yield.
