Abstract

Carbonylation of the complexes trans- MeOIr(CO)(PPh₃)₂, trans-(n-PrO)Ir(CO)(PPh₃)₂, and trans-PhOIr(CO)(PPh₃)₂ leads to carboalkoxy complexes ROC-(O)Ir(CO)₂(PPh₃)₂ in high yield. Identification of the intermediate Ir(CO)₃(PPh₃)₂⁺ OR^- indicates a two-step mechanism—first displacement of the alkoxide from the coordination sphere and then nucleophilic attack on a carbon of the cationic carbonyl complex. The hydroxy complex did not undergo carbonylation under similar conditions.
