Synthese funktionell substituierter Disilane auf der Basis von Triflatderivaten

Synthesis of Functional Substituted Disilanes on the Basis of Triflate Derivatives Functional substituted disilanes are prepared by reaction of phenylated disilanes with trifuloromethanesulfonic acid. Reduction of the triflate derivatives with LiAlH₄ leads to Si? H substituted disilanes. The chlorinated disilanes are obtained by reaction of the triflate derivatives with Et₃NHCl. Chloro-hydrogen substituted disilanes are prepared by combination of both reaction types. The preparation of these compounds in a high purity is difficult on other ways.
