Abstract
Reaction of [PtIMe(2,2′-bipyridine)], I, with MeO2CC≡CCO2Me gives first a 5 co-ordinate π-complex [PtIMe(MeO2CC≡CCO2Me)(bipy)], II, and then the product of insertion into the PtI bond[PtMe{C(CO2Me)=C(CO2Me)I}(bipy)], III. A study of the kinetics of dissociation of II to I and free alkyne shows that reaction occurs largely by dissociation of iodide followed by loss of alkyne from the resulting cationic alkyne complex. Formation of III may involve nucleophilic attack by I− on the co-ordinated alkyne of this cationic intermediate.
