Polymerized functional ionic liquid supported Pd nanoparticle catalyst for reductive homocoupling of aryl halides

摘要

Homopolymer of 3-(cyanomethyl)-l-vinylimi-dazolium hexafluorophosphate was synthesized and used as a support for Pd nanoparticles. The Pd@poly-CN-PF6 catalyst (2 mol % Pd) selectively catalyzes the reductive homocoupling reaction of aryl iodides and bromides at 100 °C in water, and the catalyst can be recycled and reused several times with slight loss of activity.
