摘要

以烯丙醚化聚合为关键步骤，合成了一系列以聚乙二醇-聚乙烯乙二醇（PEG-PVEG）共聚物为基础的双膦接枝两亲性聚合物。用紫外可见光谱、DLS和透射电镜分析了钯配合物自组装成球形胶束的过程。该胶束钯催化剂的优异催化性能在Suzuki-Miyaura水相偶联反应中得到了证明，即使在100ppm的低负载下，在2 h内也能取得显著的催化效率。

Palladium Complex Grafted on PEG-Based Amphiphilic Polymers as ppm Level Micellar Catalysts for Suzuki–Miyaura Coupling in Water

A series of bisphosphine-grafted amphiphilic polymers based on polyethylene glycol-poly(vinylethylene glycol) (PEG–PVEG) copolymers have been synthesized by using allylic etherification polymerization as a pivotal step. Self-assembling of the palladium complexes of the obtained amphiphilic polymers into spherical micelles has been investigated by UV–vis, DLS and TEM analysis. The outstanding catalytic performance of the present micellar palladium catalyst has been evidenced in the aqueous Suzuki–Miyaura coupling reaction, achieving remarkable efficiency even at a low catalyst loading of 100 ppm within 2 h.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
