Catalytic olefin metathesis based on the second- and third-row transition metals has become one of the most powerful transformations in modern organic chemistry. The shift to first-row metals to produce fine and commodity chemicals would be an important achievement to complement existing methods with inexpensive and greener alternatives. In addition, those systems can offer unusual reactivity based on the unique electronic structure of the base metals. In this Minireview, we summarize the progress of the development of alkylidenes and metallacycles of first-row transition metals from scandium to nickel capable of performing cycloaddition and cycloreversion steps, crucial reactions in olefin metathesis. In addition, we will discuss systems capable of performing olefin metathesis; however, the nature of active species is not yet known.

第一排过渡金属的烯烃复分解

基于第二和第三行过渡金属的催化烯烃复分解已成为现代有机化学中最强大的转化之一。转向第一排金属来生产精细和商品化学品将是一项重要的成就,可以用廉价和更环保的替代品补充现有方法。此外,基于贱金属独特的电子结构,这些系统可以提供不寻常的反应性。在这篇 Minireview 中,我们总结了第一排过渡金属从钪到镍的亚烷基和金属环的开发进展,这些过渡金属能够进行环加成和环回复步骤,这是烯烃复分解中的关键反应。此外,我们将讨论能够进行烯烃复分解的系统;然而,尚不清楚活跃物种的性质。
