The intramolecularity of the thermal rearrangement of 1-aryl-5-allyloxy-1H-tetrazoles 1 to 1-aryl-4-allyl-1,4-dihydrotetrazol-5-ones 2 has been investigated through cross-over studies: the results support the hypothesis for a concerted sigmatropic rearrangement occurring through a highly polar transition state, in which a partially postitively charged allyl group migrates from oxygen to nitrogen, without leaving the solvent cage.

Reaction of aryldichloroisocyanides 1a-e with sodium azide and a phase transfer agent has provided 5-chloro-1-aryl-1H-tetrazoles 2a-e in good yield. In particular, the widely-used intermediate, 5-chloro-1-phenyl-1H-tetrazole 2a, can be produced conveniently and safely in yields approaching 100%.
