摘要：

The hydroxycarbonylation of bromobenzene has been explored in a biphasic medium. Water-soluble [Pd(TPPTS)(3)] (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 [Pd(Ph)Br(TPPTS)(2)] and [Pd(COPh)Br(TPPTS)(2)] have been synthesized. A catalytic cycle is proposed.
