Abstract

The results of a kinetic study on the character (fast or slow) of a step of alkene activation in the catalytic cycle of the Mizoroki–Heck reaction with unreactive aryl chlorides in the presence of a so-called ligand-free catalytic system based on palladium are presented. An analysis of integral kinetic curves of the consumption of two competing alkenes in the reaction with aryl chloride showed that alkenes participate in a fast step of the catalytic cycle.

在无配体条件下，在未反应的芳基氯的Mizoroki-Heck反应中烯烃活化步骤的研究

摘要

在所谓的基于钯的无配体催化体系存在下，对Mizoroki-Heck反应与不活泼的芳基氯化物的催化循环中烯烃活化步骤的特征（快速或缓慢）进行动力学研究的结果被提出。对与芳基氯反应的两种竞争性烯烃消耗的整体动力学曲线的分析表明，烯烃参与了催化循环的快速步骤。
