No major difference was found between Rh- and Ir-catalyzed homogeneous carbonylation of MeOH to HOAc, using MeI as promoter. The dependence of the activity on the nature of the Ir based catalyst is greater than that of th Rh-based catalyst, and the maximum activity occurs at different conditions. Rh(CO)2I2- and Ir(CO)2I2- are the catalytic species in these reactions and the Ir complexes are the best catalysts of all the Pt metal complexes. The mechanism of the reaction is discussed.
