Homogeneous Pd-mediated catalysts have been extensively applied in petrochemical industry,fine chemistry,biological catalysis and other fields based on their good selectivity and catalytic performances during the past decades.However,the major problem in many homogeneous catalyzed organic reactions is difficult to recover the catalysts from the reaction media.From green chemistry and the sustainable development viewpoint,it is very important to develop heterogeneous Pd catalysts those combine the advantages of both homo-and heterogeneous catalysis.
