<p>Preparation of organylhydrogensilanes comprises comproportionating a mixture of organylhalosilanes in the presence of a catalyst, which contains at least one completely organically substituted ammonium or phosphonium unit. Preparation of organylhydrogensilanes comprises: comproportionating a mixture of organylhalosilanes by reaction of a organylhalosilane compound of formula (Z-R aSiCl 4-a) with organylhalosilane compound of formula (SiH bCl 4-b) to give a organylhalosilane compound of formula (Z-R aSiCl 3-a) and a organylhalosilane compound of formula (SiH b-yCl 4-b +y) in the presence of a catalyst which contains at least one completely organically substituted ammonium or phosphonium unit. R : alkyl, aryl, or alkaryl radical (optionally substituted with halo); a : 1-3; y, Z : 1-4; and b : 2-4.</p> |
