Abstract

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.
