Abstract

Irradiation of 2,2-bis(2,4,6-trimethylphenyl)hexamethyltrisilane in hydrocarbon solution produces tetramesityldisilene, which can be isolated as a yellow-orange solid stable to room temperature and above in the absence of air. Like the olefins of carbon chemistry, tetramesityldisilene undergoes addition reactions across the silicon-silicon double bond.

摘要

在烃类溶液中对2,2-双(2,4,6-三甲基苯基)六甲基三硅烷进行辐照会生成四(均三甲苯基)二硅烯,它可以被分离成一种黄橙色固体,在无空气的条件下,该固体在室温及以上温度下稳定。与碳化学中的烯烃类似,四(均三甲苯基)二硅烯会在硅-硅双键上发生加成反应。
