Some practical uses for the disilane residue from the direct synthesis of methylchlorosilanes have been proposed.This residue can be converted into organochloro-(Me2SiCl2, MeSiCl3, Me3SiCl) or organohydrochloro-monosilanes (HMeSiCl2, HMe2SiCl).These disilanes can also be used for the synthesis of alkyl (haloalkyl, alkenyl, aryl, etc.) methyldichlorosilanes or alkyl (haloalkyl, alkenyl, aryl, etc.) trichlorosilanes.The reductive properties of the Si-Si bond of these species have been utilized (e.g. in the reduction of phosphine oxides into the corresponding phosphines).Polysilanes resulting from the disproportionation of this residue are precursors of polycarbosilanes.
