By using diaryliodoniumsalts, a cylization has been accomplished in the synthesis of N-aryl phenanthridinone derivatives via a cascade of ortho-arylation and Csp2-N bond formation in the presence of palladium catalyst. The reaction exhibits a broad compatibility of readily available N-arylnaphthamides.

Analysis of the effects of added benzyl alcohol and a heavy atom (Br-) on the quantum yields for the benzophenone-sensitized reaction of the title hydroxylamine in hexadecyltrimethylammonium chloride micelles revealed that the benzoyloxy-migrated products are derived from the amidyl-benzoyloxyl radical pair that is present at the micellar surface, whereas the amidyl-phenyl radical pair that is penetrated more deeply into the micellar interior is responsible for the appearance of the phenyl-rearranged products.
