  BINOL-Salen-Co（III）盐的新型手性聚合物对二氧化碳和环氧丙烷的催化不对称环加成反应

  摘要：

  Abstractmagnified imageFour new chiral polymers of BINOL‐Salen‐cobalt(III) salt complexes have been designed, synthesized and applied to the direct fabrication of chiral propylene carbonate from racemic propylene oxide. The (R/S)‐polymer catalyst 2 and (S/R)‐polymer catalyst 4 exhibit better enantioselectivity than the (R/R)‐polymer catalyst 1 and the (S/S)‐polymer catalyst 3 and have been recovered and reused more than ten times without loss of activity and enantioselectivity.
