A novel method for the synthesis of chlorinated or partially chlorinated organosilanes and organopolysilanes. The chlorination is effected by contacting an organosilanes or organopolysilanes with anhydrous CuCl.sub.2 in a nonpolar alkane solvent, preferably pentane or hexadecane, without the use of a catalyst. Copper metal, which is easily filtered, is a reaction product. The filtrate containing the chlorinated organosilane or organopolysilane can be used directly as a reactant to produce, for example, aminoorganosilanes.
