Versuchsvorschrift

A mixture of 15.306 grams of allyl chloride, 27.09 gram of trichlorosilane and 0.04 grams of [SG]--S--Pt sufficient to provide 1×10-5 mm Pt/SiH was stirred at 23° C. under a nitrogen atmosphere. The mixture was heated to 60° C. for 16 hours. The mixture was allowed to cool to ambient temperatures and was diluted with 50 ml of hexane and filtered. The filtrate was concentrated on a rotary evaporator to give 33 grams of a clear, colorless oil. Based on method of preparation, NMR and VPC analysis there was obtained about a 92% yield of γ-chloropropyltrichlorosilane and about an 8% yield of n-propyltrichlorosilane.
