| 摘 要： | 本文利用Lewis酸催化月桂烯与丙烯酸甲酯的Diels-Alder反应,对不同的Lewis酸催化剂的催化性能进行了比较.发现无水ZnCl_2不仅能显著地提高反应速率,而且能改变加成产物中异构体的分配比例.这种催化加成的区域选择特性强烈地受到反应温度、催化剂用量及反应时间的影响,揭示出该催化反应是一平行的串行可逆反应.

| Abstract: | In this paper,some Lewis acids were used to catalyze the Diels-Alder reaction of myrcene with methyl acrylate. The catalytic properties of different lewis acid catalysts were compared. It is found that ZnCl_2 is the best catalyst. Not only does it promote reaction rate obviously, but also it can change the distribution ratio of isomers in the product. The particular regioselectivity of this catalytic cycloaddition is stronghy affected by the amounts of catalyst,reaction temperature and time. It is revealed that the catalytic reaction is a parrallel and serial reversible. |
