Abstract

Density functional theory computation for the reaction of CpPt(CO)I with PMe₃ indicates that insertion of CO into the Pt-Cp* bond of CpPt(CO)(PMe₃)I proceeds via interaction of a π orbital of Cp* with a π* orbital of CO. A similar pathway is predicted for an insertion reaction of the acetylene complex CpPt(C₂H ₂)(PMe₃)I. The conventional mechanism for CO and acetylene insertions, involving direct insertion into the Pt-C bond, is shown to be inoperative in this system.
