结构紧凑、反应活性高的双环[1.1.0]丁烷是一类最具吸引力的有机化合物。此外，双环[1.1.0]丁烷与其价态异构体（如丁二烯和环丁烯）的相互作用是有机化学中基本的周环转化之一。在此，我们报告了环三硅烯和thiatrisilabicycle [1.1.0]丁烷之间的来回相互转化，允许合成此类高反应性有机金属化合物的新代表。新合成的化合物的独特的结构和成键特征，以及它们的异构化机理，都在实验和计算上得到了验证。
Compact and highly reactive bicyclo[1.1.0]butanes constitute one of the most fascinating classes of organic compounds. Furthermore, interplay of bicyclo[1.1.0]butanes with their valence isomers, such as buta‐1,3‐dienes and cyclobutenes, is among the fundamental pericyclic transformations in organic chemistry. Herein we report the back‐and‐forth interconversion between the cyclotrisilenes and thiatrisilabicyclo[1.1.0]butanes, allowing for the synthesis of novel representatives of such classes of highly reactive organometallics. The peculiar structural and bonding features of the newly synthesized compounds, as well as the mechanism of their isomerization, were verified both experimentally and computationally.
