Abstract

A series of 1-arylsulfonyl-4-carbamoyl-1,2,3-triazol-5-olates has been synthesized. The cyclization of diazoacetamides by the action of base has been shown to be reversible for the first time. 1-Arylsulfonyl-1,2,3-triazol-5-olates undergo rearrangement upon heating to give isomeric N‑sulfonylcarbamoyldiazoacetimidolates. An equilibrium exists between these isomers in DMSO solution, which is shifted toward the acyclic derivative.
