The classical Kukhtin-Ramirez adducts, namely the 1:1 adducts of trivalent phosphorus reagents and 1,2-dicarbonyl compounds, were found more than half a century ago. Recently this family of organophosphorus compounds has regained remarkable interest from organic chemists. Relevant investigations have unveiled that Kukhtin-Ramirez adducts possess rich and appealing reactivity, particularly serving as nucleophiles, carbene surrogates or 1,1-dipoles in a series of organic reactions including insertion reaction, cyclopropanation reaction and formal (1 + 4) annulation reaction. This digest aims to summarize such encouraging advances. To give the readers a complete portrait about the chemistry of Kukhtin-Ramirez adducts, the early reports are also briefly discussed.

经典的Kukhtin-Ramirez加合物，即三价磷试剂和1,2-二羰基化合物的1：1加合物，发现于半个多世纪以前。最近，这一有机磷化合物家族已引起有机化学家的极大关注。相关研究表明，库克汀-拉米雷斯加合物具有丰富而吸引人的反应性，特别是在一系列有机反应中，包括插入反应，环丙烷化反应和正式的（1 + 4）环化反应中，用作亲核试剂，卡宾替代物或1,1-偶极子。本摘要旨在总结这些令人鼓舞的进展。为了使读者对库赫丁-拉米雷斯加合物的化学反应有一个完整的了解，还简要讨论了早期报告。
