摘要
具有较重14族元素（>E = E:, E = Si, Ge, Sn, Pb）的偏乙烯基化合物是一类独特的化合物，其中两个14族中心以不同的氧化态（+II和0）和配位态存在。由于在正式的零氧化状态下存在活性基团14元素，大多数乙烯基主要使用路易斯碱稳定，如n -杂环碳烯（NHC），硅烯（NHSi）等。这些稳定策略使得越来越多的同源和杂基偏乙烯的分离成为可能，引起了合成主基团化学界的极大兴趣。本文综述了近年来重基偏乙烯的合成、结构表征和反应性等方面的研究进展。这些偏乙烯基的反应性研究包括环加成、亲核取代、氧化加成、基团转移反应等。
Heavier Analogues of Vinylidene: Recent Advances in Syntheses and Reactivities.
Vinylidenes featuring heavier group 14 elements (>E = E:, E = Si, Ge, Sn, Pb) represent a unique class of compounds in which the two group 14 centers exist in distinct oxidation (+II and 0) and coordination states. Owing to the presence of a reactive group 14 element in a formal zero oxidation state, most of these vinylidenes are mainly stabilized using Lewis bases such as N-heterocyclic carbenes (NHC), silylenes (NHSi), etc. These stabilization strategies have enabled the isolation of a growing number of homo- and hetero-vinylidenes, garnering significant interest from the synthetic main group chemistry community. This review provides a comprehensive overview of the recent developments in the synthesis, structural characterization, and reactivity of heavier vinylidenes. The reactivity studies of these vinylidenes include cycloadditions, nucleophilic substitution, oxidative addition, group transfer reactions, etc.
