Contrary to ethoxycarbonylnitrene, selective reactions - including cyloadditions - can be carried out with benzoylnitrene. This study analyzes the sequence of reactivity of various bond types with respect to benzoylnitrene, which was generated by three different routes: direct photolysis of benzoyl azide, sensitization of azide decomposition via energy transfer, and photoinduced electron transfer...
