The coupling of coordinated isocyanide with a fragment diphosphinocarbene in the complexes fac-[Mn(CO)3(CNR){(PPh2)2CI}] (3a, R = Ph; 3b, R = tBu) leads to the formation of 4a,b, which contain the new ketenimines [(PPh2)2C=C=NR] (5a,b). The N-phenylketenimine in 4a undergoes a [4 + 1] cycloaddition by treatment with phenyl isocyanide to give 6, a neutral complex containing a unique 2-(diphosphinomethylidene)-3-imino-2,3-dihydroindole ligand.
