| 中文摘要 | Porous polymer supported palladium catalyst for cross coupling reactions with high activity has been successfully prepared by coordination of Pd2+ species with Schiff bases functionalized porous polymer. The catalyst has been systemically investigated by a series of characterizations such as TEM, N-2 adsorption, NMR, IR, XPS, etc. TEM and N-2 isotherms show that the sample maintains the nanoporous structure after the modification and coordination. XPS results show that chemical state of palladium species in the catalyst is mainly +2. More importantly, the catalyst shows very high activities and excellent recyclability in a series of coupling reactions including Suzuki, Sonogashira, and Heck reactions. Hot filtration and poison of catalysts experiments have also been performed and the results indicate that soluble active species (mainly Pd(0) species) in-situ generated from the catalyst under the reaction conditions are the active intermediates, which would redeposit to the supporter after the reactions. |
