The acetophenone-sensitized photolyses of benzoyl azide in cis- and trans-1,4-dimethylcyclohexanes gave the N-substituted benzamides stereospecifically.The photolyses in 2,3-dimethylbutane showed the same insertion regioselectivity ratio toward the C-H bonds as that of singlet benzoylnitrene in the direct photolysis.These facts indicate the existence of the singlet nitrene despite the triplet photosensitization and provide a chemical evidence for the establishment of a singlet-triplet equilibrium for benzoylnitrene.

Benzoylnitrene, generated photochemically from benzoyl azide, was inserted stereospecifically into the tertiary C-H bonds of cis- and trans-1,4-dimethylcyclohexanes.The insertion regioselectivities toward the C-H bonds were determided by use of 2-methylbutane and 2,3-dimethylbutane.The insertion proceeds involving the singlet nitrene, but not the triplet, and the photoCurtius rearrangement takes place independently of the nitrene reaction.
