摘要

N-(Phenylsulfonyl)-and N-methyl-N-(phenylsulfonyl) benzohydrazonoyl azides, prepared from the corresponding hydrazonoyl chlorides and sodium azide, undergo the cyclization to 5-phenyl-1-(phenylsulfonylamino)-1H-tetrazoles together with the competitive decomposition to benzonitriles and the Curtius-type rearrangement leading to semicarbazides when heated in benzene under reflux. The tetrazole formation of ...
