Poly(ethylene glycol) as reaction medium for mild Mizoroki–Heck reaction in a ball-mill

Abstract

Phosphine-free palladium-catalyzed Mizoroki-Heck reaction was performed using ball-milling in polyethylene glycol under mild conditions. Good to excellent yields of coupling products were obtained. This activation technique also allowed the concomitant formation of round shaped Pd-PEG nanoparticles that were characterized by TEM analysis.
