Mechanistic aspects of olefin isomerization through an alkyl chain are discussed in this review. The mechanism primarily has been categorized in two pathways: (1) metal-hydride insertion-elimination pathway; and (2) π-allyl pathway. Different mechanistic features of the two pathways are elaborated here. These features often vary among different reaction systems. Several types of experiments, such as 1,3 or 1,2-H/D exchange, crossover experiments, and other techniques, are explained. The results from different experiments are logically discussed to elucidate the mechanism for olefin isomerization.

对过渡金属催化的烯烃异构化的机理的理解：金属氢化物插入消除与π-烯丙基途径

本文综述了通过烷基链进行烯烃异构化的机理。该机理主要分为两个途径：（1）金属氢化物消除插入途径；（2）π-烯丙基途径。此处详细说明了两种途径的不同机制。这些特征通常在不同的反应系统之间变化。解释了几种类型的实验，例如1,3或1,2-H / D交换，交叉实验和其他技术。从逻辑上讨论了来自不同实验的结果，以阐明烯烃异构化的机理。
