摘要

In 1964 we,'Gilman, et uZ.,~ and Hague and Prince3 reported independently that the silicon- silicon bond has conjugating properties with phenyl and vinyl groups. Phenylpentamethyldisilane shows an intense absorption at 43,300 cm-'(E 10,900); 1 the introduction of a pentamethyldisilanyl group into benzene causes a red shift to the extent of 6000 cm-'in the 'L, band, whereas the trimethylsilyl group has only a small bathochromic ...
