本文以Watson 1983年对茂金属化合物中简并甲基配体交换的观察为出发点，对σ键的歧化反应进行了综述。这份报告包括两个主要部分。首先介绍了高氧化态金属这一关键机械步骤的识别特征和反应性特征，这些特征有一些历史背景，但为了讨论清楚，没有按历史顺序给出。第二部分提供了几个利用这种转化的精选例子，特别侧重于催化键形成反应。
A review of σ-bond metathesis is presented using Watson’s 1983 observation of degenerative methyl ligand exchange at metallocene compounds as a starting point. This review has two major parts. The first presents identifying features and reactivity characteristics of this pivotal mechanistic step for high oxidation state metals, which are given with some historical context, though not in historical order for clarity of discussion. The second part presents several selected examples of the exploits of this transformation with a particular focus on catalytic bond forming reactions.
