The UV photolysis of teh permethylated linear polysilanes Me(Me2Si)nMe (I), with n = 4 to 8, in cyclohexane at, or al little above, room temperature has been found to proceed simultaneously by two different routes, one of these involves contraction of the chain with loss of dimethylsilylene species to produce octamethyltrisilane which was usually very resistant to the photolysis), while the other comprises
发现n = 4至8的全甲基化线性聚硅烷Me(Me 2 Si)n Me(I)在环己烷中或略高于室温下的紫外光解反应通过两种不同的途径同时进行其中包括链的收缩和二甲基甲硅烷基物质的损失,从而产生通常对光解非常抗性的八甲基三硅烷),而另一种则包括对硅键的均裂,随后氢原子被形成的甲硅烷基基团夺取而形成。 1小时-聚甲基聚硅烷。从(I)在二乙基甲基硅烷中的光解表明,均相的程度随(I)链长的增加而增加,而二甲基亚甲硅烷基物质的有效产率几乎恒定,而与该链长无关。没有证据表明将光化学生成的二甲基甲硅烷基插入硅硅键中。
