The transformation of ethylene and alkenes is of high importance for the chemical industry. In this review, we focus on selective alkenes transformation where metallacyclopentane is suspected or demonstrated to be involved in the reaction mechanism. In addition to the alkenes, the “classical” products of ethylene oligomerization, we also cover articles dealing with the synthesis of cyclobutane and butadiene derivatives, through the common metallacycle intermediate. We also present studies that help decipher the precise mechanism of the transformations, i.e. involving synthesis of postulated intermediates, labelling experiments and DFT calculations.

烯烃通过金属环低聚：最新进展和机理见解

乙烯和烯烃的转化对化工行业具有重要意义。在这篇综述中，我们专注于选择性烯烃转化，其中金属环戊烷被怀疑或证明参与反应机理。除了烯烃（乙烯低聚的“经典”产品）之外，我们还涵盖通过常见的金属环中间体合成环丁烷和丁二烯衍生物的文章。我们还介绍了有助于破译转换的精确机制的研究，即涉及假定中间体的合成、标记实验和 DFT 计算。
