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.
基于第二和第三周期过渡金属的催化烯烃复分解反应已成为现代有机化学中最强大的转化反应之一。转向使用第一周期金属来生产精细化学品和大宗商品化学品将是一项重要成就，可用廉价且更环保的替代方法补充现有方法。此外，基于贱金属独特的电子结构，这些体系可呈现出不同寻常的反应活性。在本综述中，我们总结了从钪到镍的第一周期过渡金属亚烷基和金属环化合物在烯烃复分解关键反应（环加成和环逆转步骤）方面的发展进展。此外，我们还将讨论能够进行烯烃复分解反应但活性物种性质尚不清楚的体系。
