采用均相和多相两种方法合成了壳聚糖希夫碱-Cu( )配合物,用于催化苯乙烯的不对称环丙烷反应,考察了不同制备方法和不同铜含量对催化剂催化性能的影响以及催化剂的重复使用情况.当催化剂的铜含量为4.4%时,得到20.7%的ee值. The chitosan Schiff base -Cu () complexes were synthesized by both homogeneous and heterogeneous methods for the asymmetric cyclopropane reaction of styrene. The effects of different preparation methods and different copper contents on the catalytic performance of the catalysts Impact and catalyst reusability.When the copper content of the catalyst was 4.4%, an ee value of 20.7% was obtained.
