ABSTRACT:
A process for preparing carboxylic acid salts by the reaction of carbon monoxide with substituted or unsubstituted aromatic halides or an aliphatic organic halide. The process comprises the catalytic single phase carbonylation of the halide utilizing in addition to carbon monoxide, a palladium catalyst, an excess of tertiary phosphine, optionally an amine compound, with an alkali metal or alkaline earth metal base added during the reaction to form the salt.
