Article abstract of DOI:10.1016/0022-328X(94)88182-0

The hydroxycarbonylation of bromobenzene has been explored in a biphasic medium.Water-soluble (TPPTS = sodium salt of tris(3-sulphophenyl) phosphine) catalyses selectively this carbonylation reaction into benzoic acid.This complex is maintained intact in the presence of an excess of tris(3-sulphophenyl)phosphine salt.Even when a hydrogen donor is added, the reaction is limited to hydroxycarbonylation.The two complexes and have been synthesized.A catalytic cycle is proposed.Key words: Palladium; Carbonylation; Biphatic medium Phosphines; Mechanism
