Thermolysis of aryl azidometyl ketone N-methyl-N-phenylsulfonylhydrazones gave aryl 4-aryl-2-imidazolyl ketone N-methyl-N-phenylsulfonylhydrazones and arylglyoxal bis(N-methyl-N-phenylsulfonylhydrazone)s, the formation of which can be interpreted in terms of the insertion of nitrene into the α-methylene C–H bond of the original azidomethyl ketone hydrazones and the formation of an azo intermediate from the nitrene precursor, respectively. The sturctures of these products have been confirmed by an X-ray diffraction method.
