Carbon monoxide insertion reactions in [methoxy(cyclopentadiene dimer)]platinum(II) derivatives

Abstract

[Pt(C₁₀H₁₂·OMe)(PPh₃)X](X = Cl, Me, or Ph) reacts with carbon monoxide under mild conditions to give novel platinum(II) carbonyl derivatives. The reactions are interpreted in terms of a carbon monoxide insertion across the platinum–carbon σ bond, followed by displacement of the olefin by a further molecule of carbon monoxide. A possible reaction scheme is suggested.
