Abstract: Production of alkyldichlorosilanes by the copper-catalysed direct reaction of metallic silicon with alkyl chlorides involves reaction with a mixture of alkyl chloride and hydrogen chloride or another alkyl chloride which forms hydrogen chloride under reaction conditions. A method for the production of alkyldichlorosilanes of formula (3) involves the direct reaction of metallic silicon, in presence of a copper catalyst, with a mixture of: (a) an alkyl chloride of formula (1) and (b) hydrogen chloride or an alkyl chloride of formula (2) which forms HCl at reaction temperature: RCl (1) + R1Cl (2) right arrow RSiHCl2 (3) + RSiCl3 (4) R = linear, branched or cyclic 3-10C alkyl; R1 = H or a prim., sec. or tert. 4-6C alkyl group.
