A strategy to facilitate reuse of palladium catalyst stabilized by block copolymer micelles is proposed. Following this strategy, the polystyrene-b-poly(4-vinyl pyridine) micelles were firstly anchored on the surface of polystyrene-co-poly(methyl acrylic acid) core–shell microspheres to form raspberry-like colloid. Then the raspberry-like colloid was used as scaffold to support colloidal palladium catalyst. The resultant raspberry-like colloid supported palladium catalyst, which showed similar activity to the catalyst stabilized by block copolymer micelles and much improved recoverability, was demonstrated to be a good alternative for Suzuki reaction either performed in water or in DMF/water.
