A stable heterogeneous palladium catalysts, the waste eggshell membrane (ESM) anchored Pd complex, was synthesized by a simple and green technique. The catalyst obtained can display an outstanding catalytic activity for Suzuki and Heck coupling reactions in water media. The reactions of various aryl halides with aryl boronic acids and terminal alkenes provided the corresponding products in moderate to excellent yields. More importantly, this novel and efficient catalyst with high stability can be easily reused for at least twelve times with no decrease of the catalytic activity, performing an endurable and wide tolerance of the substrates. Facile synthesis, high catalytic activity, and recyclability make these catalysts interesting for further studies.

一种稳定的多相钯催化剂，废蛋壳膜（ESM）锚定的钯配合物，是通过一种简单的绿色技术合成的。所获得的催化剂对于水介质中的Suzuki和Heck偶联反应可以表现出出色的催化活性。各种芳基卤化物与芳基硼酸和末端烯烃的反应以中等至优异的产率提供了相应的产物。更重要的是，这种具有高稳定性的新颖而有效的催化剂可以容易地重复使用至少十二次而不会降低催化活性，从而对基材具有持久的耐受性。易于合成，高催化活性和可回收性使这些催化剂值得进一步研究。
