METHOD FOR PRODUCING PERHALOGENATED HEXASILANE ANION AND METHOD FOR PRODUCING A CYCLIC SILANE COMPOUND

摘要

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° C., wherein no solvent is used, and a process for the production of a cyclic silane compound of the formula Si₆R₁₂, by reacting [X]₂[Si₆Cl₁₄] with AlR₃ in 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)(H₂SiCl)]+.
