Procedure

73.2 g (725 millimol) of dichlorosilane, and 92.7 g (890 millimol) of styrene were reacted in the presence of 0.1164 g (1.68×10-4 mol) of chlorotris(triphenylphosphine)rhodium (I) as in example 3 at 100° C. for 16 hours and then the reacted liquid was distilled to obtain 147.6 g of monophenethyldichlorosilane (b.p. 95° C./7 mmHg).
