  • Process for the cleavage of silicon-silicon bonds and/or silicon-chlorine bonds in mono-, poly- and/or oligosilanes
    Patent number: 11104582
    Abstract: The invention relates to a method for cleaving silicon-silicon bindings and/or silicon-chlorine bindings in monosilanes, polysilanes, and/or oligosilanes. According to the invention, the monosilane, polysilane, and/or oligosilane is dissolved or suspended in an ether or in an ether-hydrochloric acid solution. Said method is used for example for preparing halogenated oligosilanes from halogenated polysilanes and for preparing siloxanes from organochlorosilanes and chlorinated monosilanes. Said method is particularly simple to carry out and as a result is economical.
