The present invention relates to a process for the production of perhalogenated hexasilane anion by reacting halogenated monosilane in the presence of organosubstituted ammonium and/or phosphonium halide at temperatures in a range from 100 to 120&#xb0; C., wherein no solvent is used, and a process for the production of a cyclic silane compound of the formula SiR, by reacting [X][SiCl] with AlRin at least one organic solvent, wherein R is chlorine or methyl and X, the same or different, is a counter-cation and is preferably selected from organosubstituted ammonium, organosubstituted phosphonium, alkali metal ions and [(PEDETA)(HSiCl)]+.

Method for producing perhalogenated hexasilane anion and method for producing a cyclic silane compound

Triphenylgermylsilane (PhGe&#x2014;SiH) is useful for the production of germanium-silicon layers (Ge&#x2014;Si) or as transfer agent of silane groups (SiH). Further, a method describes the production of triphenylgermylsilane (PhGe&#x2014;SiH) by reducing trichlorosilyl-triphenylgermane (PhGe&#x2014;SiCl) with a hydride in solution, and another method describes the production of trichlorosilytrichlorogermane (ClGe&#x2014;SiCl) by reacting trichlorosilyltriphenyigermane (PhGe&#x2014;SiCl) with hydrogen chloride (HCl) in the presence of AlClin solution. In addition, trichlorosilyltrichlorogermane is also used for the production of germanium-silicon layers (Ge&#x2014;Si).
