合成了具有两个手性硅中心的非对映体可分离的 1,2-二氯乙硅烷。通过还原反应，两种非对映体乙硅烷都提供了相同的空气极不稳定的E-二硅烯。此外，为了获得二硅烯形成的进一步实验证据，我们进行了相应的二溴硅烷的还原反应作为二硅烯的替代合成路线，根据条件形成了具有不对称全硅三元骨架的环丙硅烷作为副产物。根据这些实验结果和支持的DFT计算，我们为研究二硅烯的合成机理找到了一些线索。
Diastereomerically separable 1,2‐dichlorodisilanes possessing two chiral silicon centers were synthesized. By the reduction reaction, both diastereomeric disilanes afforded the same extremely air‐unstableE‐disilene. In addition, to get further experimental evidence for the formation of the disilene, we performed the reduction reaction of the corresponding dibromosilane as an alternative synthetic route toward the disilene, which resulted in the formation of a cyclotrisilane having an asymmetric all‐silicon three‐membered skeleton as a co‐product depending on the conditions. As a result of these experimental results and the supporting DFT calculations, we found some clues for the investigation into the synthetic mechanism of disilenes.
