The interaction of silicon-silicon-bonds and phenyl-systems in phenyldisilanes and the resulted characteristic UV absorptions have been one of the fundamental issues of organosilicon chemistry. However, the interaction between two phenyl groups and the central silicon-silicon bond in 1,2-diphenyltetramethyldisilanes and its correlation with the characteristic UV absorptions remain uncompletely solved. In this paper, a series of unsymmetric substituted 1,2-diphenyltetramethyldisilanes, namely C6H5SiMe2SiMe2C...
饱和硅硅键不仅具有较高的最高占有轨道(HOMO),而且具有较低的最低空轨道(LUMO),因而表现出类似于不饱和碳碳键的许多特性,例如硅硅键和苯环之间可以发生特殊的相互作用,后者是有机硅化学350 http://sioc-journal.cn/?2014 Chinese Chemical Society&SIOC,CAS Chin.J.Org.Chem.
