The reaction mode of the nickela five-membered ring complexes, prepared from phenyl isocyanate and the alkenes ethene, propene and styrene at (Lig)Ni0 systems, with oxidizing reagents such as FeCl3 and iodine are reported. Depending on the ligands, either unsaturated acid amides are formed or α,ω-diacid amides result by intermolecular CC bond formation. In this way the azanickela seven-membered ring
