Abstract

A method for converting organosilanes by reacting at least one silane (1) of the general formula RaSiCl4-a  (I) with at least one further silane (2) of the general formula RbSiCl4-b  (II) wherein silane (2) is identical or different from silane (1), optionally with additional use of silanes (3) which contain Si-bonded hydrogen and have the formula RdHeSiCl4-d-e  (III) in the presence of aluminum salts, preferably aluminum halides, as catalysts and in the presence of cocatalysts, to obtain at least one silane (4) which differs from silanes (1) and (2) and has the general formula RcSiCl4-c  (IV).
