The 1-cyclohexenylmethoxycarbonyl complex Pt(CO2Me)(C6H9)(dppp) (dppp = 1,3-bis(diphenylphosphino)propane, Ph2PCH2CH2CH2PPh2) undergoes irreversible insertion of CO into the Pt-C6H9 bond under ambient conditions to give Pt(CO2Me)(COC6H9)(dppp), which may contain a dihapto-acyl group; the analogous 1-cyclohexenyl complexes containing 1,2-bis(diphenylphosphino)ethane and cis-1,2-bis(diphenylphosphino)ethylene are unreactive under the same conditions.
