Abstract

Reaction of CO with trsans-Ir(CO)(Cl)L₂ (L = PPh₃ in toluene and DMSO; L = TPPMS in DMSO and H₂O, TPPMS = PPh₂(m-C₆H₄SO₃Na)) reversibly produces Ir(CO)₂(Cl)L₂ or [Ir(CO)₃L₂]Cl depending on the solvent polarity. The solvent polarity has a small effect on the rate of reaction with CO; the rate constants in toluene, DMSO and H₂O are all within a factor of two. Comparison to the reaction with H₂ shows that the selectivity for CO is much greater (k_CO/k_H2 = 150) in toluene than in water (k_CO/k_H2 = 5).
