31P NMR studies show that the complexes trans-[Pt(SnCl3)PhL2] (L = PPh3 or PMePh2) react with carbon monoxide by an initial, rapid displacement of the trichlorostannate ligand to yield trans- [PtPh(CO)L2]+SnCl3-. Further reaction to produce trarcs-[Pt(SnCl3)(COPh)L2] occurs slowly in the absence of free CO (L = PPh3 or PMePh2) by initial nucleophilic attack of Sncl3-, but in the presence of excess CO an alternative route involving phosphine dissociation (L = PPh3 only) operates. Comparative studies with other anions have led to a reinterpretation of the role of the trichlorostannate ligand in carbonylation and decarbonylation reactions of organoplatinum(II) complexes.
