제목 Macroporous Polystylene-Supported N-Heterocyclic Carbene Palladium Catalyst for Efficient Suzuki Reaction
초록 Macroporous polystylene(MPS)-supported 1-mesitylimidazolium chloride resin was prepared by treating macroporous chloromethyl polystylene with 1-mesitylimidazole as a supported N-heterogeneous carbine(NHC) precursor for immobilization of palladium catalyst. This N-heterogeneous carbine(NHC) precursor readily formed a stable complex with Pd(OAc)2, which was identified by FT-IR, FE-SEM and ICP analysis. The MPS-supported NHC-Pd catalyst with the bulky ligand group efficiently catalyzed the suzuki cross-coupling under mild condition and showed outstanding reusability without any loss of catalytic activity in Suzuki cross coupling reaction.
