PHOTOSENSITIZED OXYGENATION OF 3-DIAZOCAMPHOR

Okada, Keiji,Mukai, Toshio

, p. 359 - 360 (1980)

Photosensitized oxygenation of 3-diazocamphor gave camphorquinone and camphoric anhydride in benzene.The yield of camphoric anhydride did not depend on the concentration of added camphorquinone or of diazocamphor.When the reaction was carried out in acetonitrile or benzonitrile, amide 7 or 8 was produced.The formation of amide strongly supports the intermediacy of carbonyl oxide.
