Abstract : New polysilanes bearing different alkoxy groups attached directly to silicon atoms were prepared by the displacement of the phenyl groups in the poly(phenylmethylsilylene) by trifluoromethanesulfonic acid and the subsequent reaction with alcohols in the presence of different bases. This reaction was also studied for model compounds. Thus, different disilanes were converted to the 1,2-bis(trifluoromethanesulfonyloxy) tetramethyldisilane and subsequently to the corresponding 1,2-dialkoxydisilanes.
