ELECTROPHILIC SUBSTITUTION OF HYDROGEN IN DIAZOACETONITRILE

Morzherin, Yu. Yu.,Kolobov, M. Yu.,Shafran, Yu. M.,Bakulev, V. A.

, p. 1454 - 1456 (2007/10/02)

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.
