The zwitterionic rhodium complex, (COD)Rh(η6-C6H5BPh3) (1), can catalyze the carbonylation of benzylic and allylic bromides in the presence of 5 N NaOH and CH2Cl2 at atmospheric pressure and 40 deg C, with (C6H13)4N+ HSO4- as the phase transfer catalyst, to give carboxylic esters as the major products.
