The reaction of 4-carbethoxy-5-chloro-1,2,3-thiadiazole (1) with sodium azide results in the formation of ethyl α-thiatriazolyldiazoacetate (3) instead of the corresponding azide (2).Two plausible mechanisms for this new rearrangement are formulated.

2-Carbonyl-substituted diazoacetonitriles were obtained by the reaction of diazoacetonitile with carboxylic acid chlorides and isocyanates.The acyl derivatives of diazoacetonitriles were identified in the form of the corresponding triphenylphosphazines.The carbamoylation products undergo cyclization to 1-substituted 4-cyano-5-hydroxy-1,2,3-triazoles in the course of the reaction.
