Organylhydrogensilanes are prepared by means of a comproportionation reaction according to the equation n nZ R a SiCl 4−a +SiH b Cl 4−b →Z R a SiHCl 3−a +SiH b−y Cl 4−b+y , nin the presence of a catalyst which contains at least one completely organically substituted ammonium or phosphonium unit, where R is an optionally halogen-substituted alkyl, aryl, or alkaryl radical, a is 1, 2 or 3, y and Z are 1, 2, 3 or 4 and b is 2, 3 or 4. |
