Coordination chemistry of perhalogenated cyclyopentadienes and alkynes - XXI. Studies on the substitution reactions of Pt(PPh3)2(C2Cl2) and trans-Pt(PPh3)2(Cl)(C2Cl) with triphenylphosphite

The reactions of the Pt(O) π-alkyne complex Pt(PPh3)2(Cl C≡CCl) and the PtII alkynyl complex Pt(PPh3)2(Cl)(C≡CCl) with P(OPh)3 lead to either the π-alkyne complexes Pt(PPh3)n(P(OPh)3)2-n(Cl C≡CCl) (n = 0, 1) or the cis and trans isomers of Pt(PPh3)n[P(OPh)3]2-n (Cl)(C≡CCl) (n = 0, 1), depending on the reaction conditions. The course of the reaction was followed by 31P-NMR spectroscopy, from which a plausible mechanism for the oxidative addition reaction can be derived: key steps are phosphine dissociation from the Pt(0) species to a two-coordinate intermediate, which undergoes oxidative addition of a C - Cl bond to give a three-coordinate PtII species, which might be stabilized by dimerization.
