The cationic cis- and trans-IrX(CO)(dppe)2 2+ (X = H, Cl) species react with nucleophiles, such as H20, OH-, and H-, to afford hydroxycarbonyl and formyl cations of Ir(III) typified by the species trans-IrH-(COOH)(dppe)2 + and trans-IrX(CHO)(dppe)2 +. The formyl complexes are protonated by strong acids to afford the electrophilic dicationic hydroxycarbene complexes trans-IrX(CHOH)(dppe)2 2+. Reactivities and stabilities of these species are discussed.
