Reaction of (Me5C5)PNBut with [(R3P)2Ni(cod)](cod = cyclo-octa-1,5-diene)(R = Et, Bu, or Ph) produces complexes [(R3P)2Ni(C5Me5)PNBut], which rearrange to yield the novel metal-substituted iminophosphanes, [(R3P)(η5-C5Me5)NiâPNBut] and free phosphane R3P, the new complexes being identified by means of n.m.r. spectroscopy; similarly, the metallophospha-alkenes, [(R3P)(η5-C5Me5)NiâPC(SiMe3)2] are formed via reaction of (Me5C5)PC(SiMe3)2 and [(R3P)Ni(alkene)2].
