| 中文摘要 | A highly efficient chiral-bridged biphenyl diphosphine ligand [(Rax)-BuP] modified cationic palladium(II) catalyst system for the synthesis of optically active polyketone by stereoselective alternating copolymerization of propene and carbon monoxide is reported for the first time. The results show that [Pd(MeCN)4][OTf]2 is an excellent catalyst precursor in a mixed solvent of MeNO2–MeOH. The highest catalytic activity was found to be 221 g polymer/(g Pd·h). A chiral polyketone with molecular weight Mn = 2.9 × 104, polydispersity = 1.4, and molar optical rotation = +37° was afforded under optimized reaction conditions. |
