摘要:

基于合成化学领域的最新研究成果,凝练出一类以“催化进程分离”为特征的新型催化串联反应。该类反应中各步反应从时间进程上先后分别发生,各自独立进行、互不影响,具有与《物理化学》教科书中传统催化串联反应明显不同的动力学特征。本文以一典型反应为例,介绍该类反应的基本特征及其在合成化学领域的重要性,并基于文献中量子化学计算结果合理解释了“进程分离”的微观本质,给出了理解该类动力学特征的一般理论模型。

Abstract:

Based on the latest research results in the field of synthetic chemistry, a new type of catalytic tandem reactions characterized by "separation of the catalytic processes" have been developed. In such reactions, each step of the reaction takes place successively in time, and each step is independent and does not affect the others. Taking a typical reaction as an example, in this paper, the basic characteristics of this type of reaction and its importance in the field of synthetic chemistry are introduced, and a theoretical model is established to understand the kinetic characteristics of this type of reaction based on the results of quantum chemistry calculations found in the literature.

Key words: Tandem reaction, Catalysis, Process separation, Theoretical model
