Abstract
Silicon compounds having Si—H groups are converted into silicon compounds having Si—X groups by reaction with HX in the gas phase in the presence of a quaternary ammonium or phosphonium halide catalyst or an ionic chloride of a heterocycle organically substituted on the heteroatom.

A process for converting silicon compounds which have Si—H bonds into silicon compounds which have Si-halogen bonds, comprising reacting the silicon compounds having Si—H bonds in the gas phase with hydrogen halide in the presence of at least one catalyst selected from the group consisting of
- (a) tetraorganophosphonium halides,
- (b) tetraorganoammonium halides, and
- (c) ionic halides of heterocycles which are organically substituted on the heteroatom.
