Procedure

Dichlorosilane (31.7 g) (314 millimols), styrene (56.3 g) (541 millimols) and chlorotris(triphenylphosphine)rhodium (0.2182 g) (2.36×10-4 mol) were nitroduced into a 200 ml stainless steel reactor, which was then closed. Reaction was carried out with stirring on heating in an oil bath at 150° C. for 20 hours. The resulting reaction liquid was distilled in vacuo to obtain 45.7 g of mono-β-phenylethyldichlorosilane.
