Improved Preparation of 5-Chloro-1-phenyl-1H-tetrazole and Other 5-Chlorotetrazoles.
摘要:
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%.
