AbstractThe mechanism of methanol carbonylation catalyzed by a chelated square planar carbonyl rhodium complex was studied. The chelated square planar cationic complex was formed via the coordination of [Rh(CO)(2)Cl](2) with the ligand, which has two donors with different coordination capacity. Experimental results showed that the active species of the catalyst in methanol carbonylation differed from [Rh(CO)(2)I(2)](-) reported in other literature. Other than conventional concept, the N -> Rh bond, formed by rhodium in the complex and nitrogen at pyridine ring in the ligand, did not break in the course of the carbonylation reaction, but formed into new active species instead, i.e., the ligand and rhodium as a whole participated in the oxidative addition of CH(3)I and the formation of CH(3)COI Via the investigation of the corresponding catalyst with polymer ligand, the mechanism was further demonstrated. The result is of significance towards the molecular design of such catalysts, and the solution to their deactivation due to precipitation in industrial application as well.
