二硅烷的光解反应,一直是有机硅化学中一个引人注目的课题。人们已经对多种芳基二硅烷的光解反应作了比较系统的研究,但却很少见到对含杂环基二硅烷的研究。通常,芳基二硅烷的光解反应按三种途径进行。以甲醇为捕捉剂时,其反应机理如图1所示。
The photodegradation of disilane has been an attractive topic in organosilicon chemistry. A variety of aryldisilanes photolytic reaction has been made more systematic study, but rarely found on the heterocyclic ring disilane. In general, photodissociation of aryldisilanes proceeds in three ways. Methanol as a capture agent, the reaction mechanism shown in Figure 1.
