論文簡(jiǎn)介

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.
