5-Substituted tetrazoles 13, readily prepared from RCN and aluminium azide, react rapidly with Appel salt 1 at room temperature to give hydrazonoyl chlorides 16 in high yield. 5-Aminotetrazole 4 reacts further to give the extended bis(iminodithiazole) 6 and a minor product 7. Mechanisms are proposed for these reactions (except for the formation of 7) which are supported by the smooth conversion of
