相转移催化剂与反应机理的结构适应性研究

摘要

有机化学反应中，催化剂的选择关系到有机物合成的效率及产物的纯度，为了提高催化剂的研制效率，缩小催化剂的选择范围，对某些季铵盐类相转移催化剂与反应速率、产物组成之间的关系进行了研究。结果表明：适宜的催化剂，其结构往往与反应机理相适应。%The selection of catalysts is of vital importance to the efficiency of organic synthesis and the purity ofproducts in organic reactions. In order to improve the catalyst developing efficiency and reduce the scope of catalyst selection, the relationship between the reaction rate, product composition and phase transfer catalysts of quaternary ammonium is fully studied and the result shows that the structure of the optimum catalysts often adapts to the reaction mechanism.
