A Facile Synthesis of 2,5-Disubstituted Tetrazoles by the Reaction of Phenylsulfonylhydrazones with Arenediazonium Salts

Abstract 2,5-Disubstituted tetrazoles are obtained in good yields by the reaction of phenylsulfonylhydrazones of aromatic aldehydes (and cinnamaldehyde) with arenediazonium salts. From the synthetic viewpoint for tetrazoles, this method may be of high synthetic utility on account of the availability of starting materials, the simplicity of procedure, and higher yields.
