| 摘 要： | 以聚氯乙烯为载体,合成两种负载型催化剂水解聚氯乙烯四乙烯五胺负载L-脯氨酸催化剂(HPTP)和聚氯乙烯四乙烯五胺负载L-脯氨酸催化剂(PTP),催化剂中脯氨酸负载量分别为2.46 mmol/g和1.52 mmol/g。两种催化剂均可实现对不对称Aldol反应的催化,但HPTP的活性和选择性均较PTP的高。HPTP在水中可以催化多种苯甲醛与丙酮的不对称Aldol反应,取得中等的ee值。HPTP经过回收还可以重复利用,显示了较好的性能。在合适的反应条件下,HPTP催化对硝基苯甲醛和丙酮的反应,获得最高75%的产率和39%的ee值。 |

| Abstract: | Two different catalysts,Polyvinyl chloride-tetraethylenepentamine supported L-proline(PTP) and hydrolyzed polyvinyl chloride-tetraethylenepentamine supported L-proline(HPTP),were prepared with simple method from polyvinyl chloride.The content of L-proline in the catalyst was 2.46mmol/g and 1.52mmol/g respectively.The asymmetric Aldol reaction can be catalyzed effectively by HPTP or PTP.However,the activity and selectivity of HPTP was higher than PTP.HPTP could be reused for Aldol reaction after being recycl... |
