摘要/Abstract

摘要： 环内金属卡拜是一类具有环内金属-碳三重键的金属有机化合物，其环张力与金属-碳键的协同作用赋予该类体系独特的理化性质。本文综述了环内金属卡拜的研究进展，涵盖其主要合成策略与反应化学，重点讨论五元环内金属卡拜芳香性及环张力效应对其结构稳定性与反应行为的影响，并阐述基于卡拜碳双亲性特征的反应规律。将此类前沿研究引入本科金属有机化学课程教学，有助于拓展教学内容、提升学生兴趣，并激发其创新思维与研究热情。

关键词: 环内金属卡拜, 环张力, 双亲性, 芳香性, 金属-碳键

Abstract: Endocyclic metal carbynes represent a distinctive class of organometallic compounds characterized by metal-carbon triple bonds within cyclic frameworks. The synergistic effects of ring strain and metal-carbon bonding confer unique physicochemical properties to these systems. This review comprehensively examines recent advancements in endocyclic metal carbyne chemistry, encompassing synthetic methodologies and reaction mechanisms. Special attention is given to the aromaticity and ring-strain effects in five-membered cyclic metal carbynes, elucidating their impact on structural stability and reactivity patterns. The reaction behaviors governed by the amphiphilic nature of the carbyne carbon are systematically discussed. Incorporating these cutting-edge research findings into undergraduate organometallic chemistry curricula serves to enrich course content, enhance student engagement, and foster innovative thinking and research enthusiasm.

Key words: Endocyclic metal carbynes, Ring strain, Amphiphilicity, Aromaticity, Metal-carbon bond
