Abstract：
In this review, the current state of affairs in the novel field of the group 14 element clusters based on the bicyclo[1.1.0]butane framework, namely, bicyclo[1.1.0]butane, [1.1.1]propellane, and tricyclo[2.1.0.02,5 ]pentane derivatives, are overviewed. Structural similarities and differences between these three classes of highly strained polycyclic compounds are considered from the viewpoint of the critically important nature of their bridgehead bonds. Synthetic strategies towards bicyclo[1.1.0]butanes, [1.1.1]propellanes, and tricyclo[2.1.0.02,5 ]pentanes, as well as their peculiar structural and bonding features, and specific reactivity, are also presented and discussed in this review.
摘要：
在这次审查中,基于双环[1.1.0]丁烷框架的第14族元素簇的新领域的现状，即,双环[1.1.0]丁烷,[1.1.1]propellane,和三环[2.1.0.02,5]戊烷衍生物，被概述。从桥头键的至关重要性质的角度考虑了这三类高应变多环化合物之间的结构相似性和差异。双环[1.1.0]丁烷的合成策略，[1.1.1]推进剂，和三环[2.1.0.02,5]戊烷，以及它们独特的结构和结合特征，和特定的反应性，在这篇综述中也进行了介绍和讨论。
