could be soaked with palladium(0) from palladium salts, the formate counteranion being the reducing source. The resulting Amberlite resin formate supported with palladium(0), ARF-Pd, showed excellent catalytic activity in Heck, Suzuki-Miyaura, and Sonogashira couplings with a range of substrates. The catalyst may be recovered easily and quantitatively without leaching and recycled; it was tested for
可以通过用甲酸水溶液简单漂洗而得自市售Amberlite树脂氯化物的聚离子Amberlite树脂甲酸盐(ARF)可以用钯盐中的钯(0)浸泡,甲酸的抗衡阴离子是还原性来源。负载有钯(0),ARF-Pd的所得Amberlite树脂甲酸酯在Heck,Suzuki-Miyaura和Sonogashira偶联剂中与多种底物均表现出出色的催化活性。该催化剂可以容易地定量回收而无需浸出和再循环。对它进行了五次运行测试,没有任何明显的活性损失。 Amberlite树脂-CC偶联-非均相催化-钯
