The photochemistry of N-phenylhydroxylamine (9) has been examined in the so
lution phase and in the solid state. The major products are aniline and nit
rosobenzene. The nitrosobenzene quickly reacts with 9 to generate azoxybenz
ene and with aniline to produce azobenzene. The quantum yields for the disa
ppearance of 9 are reasonably high (0.25-0.29) and suggest that the photoch
emical reactions proceed from a hydrogen-bonded dimer. (C) 1999 Elsevier Sc
