A general method for the synthesis of 5-aminotetrazoles is outlined using the mercury(II)-promoted attack of azide anion on a thiourea. The reaction proceeds through a guanyl azide intermediate, which undergoes electrocyclization to the tetrazole. The method is high yielding and provides access to mono-, di-, and trisubstituted 5-aminotetrazoles, targets of potential interest for combinatorial library
