In this paper, a new method for the preparation of microcapsule-supported palladium catalyst for Suzuki coupling reaction was described. The highly monodispersed cross-linked polystyrene microcapsules containing phosphine ligand were synthesized by the self- assembling of phase separated polymer (SaPSeP) method using diphenyl (4-vinylphenyl) phosphine and divinylbenzene as a monomer and cross-linking agent, respectively, and 2 ...
