The oxidative cyclization of some aldehyde semicarbazones 1O with four different oxidizing agents has been effected.The structure of the semicarbazones and the nature of cyclizing agent affected the rate and yield of cyclization but they did not show any influence on the regiochemistry of reaction.In fact, 1,2,4-triazoline 2O was the only heterocyclic ring obtained by the cyclization reaction.
