Title
Palladium nanoparticles immobilized by click ionic copolymers: Efficient and recyclable catalysts for Suzuki–Miyaura cross-coupling reaction in water
Abstract

Click reaction of alkyne-functionalized imidazolium salts with azide-containing copolymers gave rise to the click ionic copolymers, subsequent complexation with palladium acetate and reduction using NaBH4 gave rise to palladium nanoparticles (NPs). The NPs demonstrated high catalytic activity in Suzuki–Miyaura cross-coupling reaction of aryl bromides in pure water. The catalytic system can be used at least five times, no obvious loss of catalytic activity is observed after the reaction.
