摘要：
The photochemistry of N-phenylhydroxylamine (9) has been examined in the solution phase and in the solid state. The major products are aniline and nitrosobenzene. The nitrosobenzene quickly reacts with 9 to generate azoxybenzene and with aniline to produce azobenzene. The quantum yields for the disappearance of 9 are reasonably high (0.25-0.29) and suggest that the photochemical reactions proceed from a hydrogen-bonded dimer. (C) 1999 Elsevier Science S.A.
