under gas-phase flow conditions, to lose Ph₃PO and benzyl radicals to afford new heterocyclic products resulting from dominocyclization of both C- and N-centered radicals. Most products arise from processes of the former type and have quinoline, phenanthridine, or ring-fused phenanthridine structures, while in one case, a process of the latter type leads to a benzocarbazole product.

Gas-phase cyclization processes of stabilizedphosphorusylides bearing a suitably substituted 2-aminophenyl group lead efficiently either to 3-substituted quinolines or benzo[c]carbazole and heterocyclic-fused analogues depending on the substituents present.
