Thermolysis of Aryl Azidomethyl Ketone N-Methyl-N-phenylsulfonylhydrazones

Article abstract of DOI:10.1246/bcsj.67.1100

Thermolyis of aryl azidomethyl 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 structures of these products have been confirmed by an X-ray diffraction method.
