The reaction of phenylnitrene with oxygen was reinvestigated by irradiating phenyl azide (1) in O2-saturated acetonitrile solutions.Quantum yields of the disappearance of 1 are calculated from absorption spectral changes, and primary photoproducts are determined by using high-pressure liquid chromatography.The photochemistry of the reaction products (azobenzene, azoxybenzene, nitrobenzene, and nitrosobenzene) are also examined, including measurements of quantum yields and determinations of primary photoproducts and product ratios.A reaction sequence is presented to account for the photooxidation products afforded upon irradiation of 1 in the presence of oxygen.The reaction of phenylnitrene with oxygen is an effective termination step in the autocatalytic chain decomposition of 1.
