Abstract
The invention relates to a process for preparing monomeric and/or dimeric halogen- and/or hydrogen-containing silicon compounds from oligomeric inorganic silanes having three or more directly covalently interconnected silicon atoms substituted by substituents selected from halogen, hydrogen and/or oxygen by reacting the oligomeric silane over a nitrogen-containing catalyst in the presence of hydrogen halide.
