Abstract:
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.
