In organic chemistry, olefin–olefin metathesis of two unsaturated substrates for the formation of a new carbon–carbon bond has been widely explored and applied. Exploration of the construction of a carbon–carbon bond through the carbonyl–olefin metathesis reaction remains limited but has recently attracted significant interest and attention. This review covers most of the strategies involving metal-mediated, metal-free intramolecular, photochemical, Lewis acid-mediated, and catalytic carbonyl–olefin metathesis (e.g., ring-closing metathesis, ring-opening metathesis, and cross-metathesis). The necessity of stoichiometric amounts of transition metals with the synchronized formation of kinetically inert metal oxo species, which prevented the regeneration of the active metal catalyst, has most likely been the main reasons for the insignificance of the carbonyl–olefin metathesis reaction. Developing catalytic carbonyl–olefin metathesis is still a current challenge in organic synthesis.

羰基-烯烃复分解：一项重要综述

在有机化学中，人们广泛探索并应用了两个不饱和底物的烯烃-烯烃复分解反应以形成新的碳-碳键。通过羰基-烯烃复分解反应构建碳-碳键的探索仍然有限，但最近引起了极大的兴趣和关注。这篇综述涵盖了涉及金属介导，无金属的分子内，光化学，路易斯酸介导和催化羰基-烯烃复分解的大多数策略（例如，开环复分解，开环复分解和交叉复分解）。化学计量数量的过渡金属与动力学惰性金属氧代物种同步形成的必要性，阻止了活性金属催化剂的再生，很可能是羰基-烯烃复分解反应无关紧要的主要原因。发展催化羰基-烯烃复分解反应仍然是有机合成中的当前挑战。
