The photolysis of tris(trimethylsilyl)silane (TTMSS) was studied in the absence and in the presence of added trapping agents such as alkenes and alcohols. It was found that, unlike the case with pyrolysis, silyl radicals rather than silylenes are produced. They may be efficiently trapped with alkenes, to give the hydrosilylation products, but not with alcohols. The major product from the photolysis
在不存在和存在添加的捕集剂(如烯烃和醇)的情况下研究了三(三甲基甲硅烷基)硅烷 (TTMSS) 的光解。发现与热解的情况不同,产生的是甲硅烷基自由基而不是甲硅烷基。它们可以被烯烃有效地捕获,得到氢化硅烷化产物,但不能被醇捕获。在不添加捕集剂(或使用醇作为捕集剂)的情况下,TTMSS 光解的主要产物是四(三甲基甲硅烷基)硅烷。介绍了解释光产物的可能机制。关键词:氢硅烷,光解,亚甲硅烷,甲硅烷基自由基,甲硅烷基氢化物。
