合成并表征了一种新的聚苯乙烯锚定的Pd(II)苯基二硫代氨基甲酸酯配合物。在有氧条件下，该Pd络合物在Heck偶联和无铜Sonogashira偶联反应中起到了高效的多相催化作用。此外，该催化剂具有良好的热稳定性和可回收性。(C)2012爱思唯尔有限公司。保留所有权利。
A new polystyrene-anchored Pd(II) phenyldithiocarbazate complex is synthesized and characterized. This Pd-complex behaves as an efficient heterogeneous catalyst in the Heck coupling and copper-free Sonogashira coupling reactions under aerobic conditions. Furthermore, the catalyst shows good thermal stability and recyclability. (C) 2012 Elsevier Ltd. All rights reserved.
