Direct Involvement of the Acetato Ligand in the Reductive Elimination Step of Rhodium-Catalyzed Methanol Carbonylation
Résumé
For the last step of rhodium-catalyzed methanol carbonylation, high-pressure NMR, and kinetic and experimental data supported by density functional theory calculations are consistent with substitution of I– by an AcO– ligand on the [RhI3(COCH3)(CO)2]− species followed by reductive elimination of acetic anhydride, which immediately reacts with water to afford acetic acid.
