A series of new MCM-41 supported carboxyl Pd(Ⅱ) complexes were prepared and their catalytic performance in the Heck arylation of alkenes was studied.The results indicated that the MCM—(COOH)2·Pd(Ⅱ) complex exhibited high catalytic activities
stereo-selectivities and stabilities in the arylation of aryl iodides with styrene
acrylic acid and methyl acrylic at 70℃ in the solvent system of Et3N-DMF or Bu3N-DMF
and was significantly better than SiO2 supported carboxyl Pd(Ⅱ) complex.
