A series of N-β-naphthalenesulfonylbenzohydrazidoyl chlorides 8a-d has been prepared by the action of thionyl chloride on the corresponding hydrazides 7a-d.Treatment of 8 with triethylamine and morpholine afforded the tetrazines 10 and the amidrazones 11 respectively.Acid hydrolysis of 11 yielded the hydrazides 7.Reaction of 8 with phenylhydrazine gave 3,5-diaryltetrazoles 14.However, reaction of 8 with aroylhydrazines yielded 3,5-diaryl-4-β-naphthalenesulfonylamino-4H-1,2,4-triazoles 15.The structures of the products were assigned upon the basis of their spectra, elemental analyses and alternative synthesis whereever possible.
