Dimeric cyclometallated oxime palladium complex containing palladium-carbon
covalent bond was found to efficiently catalyze the carbonylation
reactions of aryl iodides with various alcohols to give esters in
excellent yields with high selectivity. These complexes were also
stable under a carbon monoxide atmosphere at high temperatures.
