A polymer-supported terpyridine palladium complex was prepared. The complex was found to promote hydrodechlorination of aryl chlorides with potassium formate in seawater. Generally, reductive cleavage of aryl chlorides using transition metal catalysts is more difficult than that of aryl bromides and iodides (reactivity: I > Br > Cl); however, the results obtained did not follow the general trend. Therefore
制备了聚合物负载的三联吡啶钯配合物。发现该配合物可促进芳基氯与甲酸钾在海水中的加氢脱氯。通常,使用过渡金属催化剂对芳基氯化物的还原裂解比芳基溴化物和碘化物更难(反应性:I > Br > Cl);然而,获得的结果并未遵循总趋势。因此,我们研究了反应抑制剂并找到了去除这些抑制剂的方法。聚合物催化剂在海水中的转移还原方面表现出高催化活性和高可重复使用性。
