A new method for the preparation of microcapsule-supported palladium catalyst was described.The highly monodisperse crosslinked 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 crosslinking agent,respectively, and 2,2’-azobisisobutyronitrile(AIBN) as an initiator within the droplets of oil-in-water(O/W) emulsions,which were prepared by using the Shirasu Porous Glass(SPG) membrane emulsification technique.The prepared microcapsule-supported palladium catalyst exhibited high catalytic activity for Heck reaction and can be reused several times without loss of activity.
