allylation using allylic alcohol is an environmentally‐friendly method because of water being the sole byproduct in such reactions, allylic alcohol is one of the most difficult allylating agents in Pd‐catalyzed allylation of nucleophiles. In this study, we successfully developed a mesoporous silica‐supported Pd complex as an efficient catalyst for the allylation of nucleophiles using allylic alcohols as allylating
尽管使用烯丙醇进行烯丙基化是一种环境友好的方法,因为水是此类反应的唯一副产物,但烯丙醇是钯在亲核试剂的Pd催化烯丙基化中最困难的烯丙基化剂之一。在这项研究中,我们成功地开发了介孔二氧化硅负载的Pd配合物,它是使用烯丙醇作为烯丙基化剂进行亲核试剂烯丙基化的有效催化剂。烯丙醇被载体表面的硅烷醇基团活化,很容易进行π-烯丙基铝中间体的形成。负载的Pd配合物的催化活性为。比其均质前驱体Pd络合物高9倍。基于钯的最高营业额达到4500。各种亲核试剂和烯丙醇衍生物可以用作底物。
