    摘要: The invention relates to a method for producing perhalogenated hexasilane anion by reaction of halogenated monosilane in the presence of organo-substituted ammonium halide and/or organo-substituted phosphonium halide at temperatures in a range of 100 to 120°C, without using solvent, and to method for producing a cyclic silane compound of the formula Si
    6 R
    12 by reaction of [X]
    2 [Si
    6 Cl
    14 ] with ALR
    3 in at least one organic solvent, with R being chlorine or methyl and X being the same or different and a counter-cation and being preferably selected from organo-substituted ammonium, organo-substituted phosphonium, alkali metal ions and [(PEDETA)(H
    2 SiCl)]
    + .
