[CH2:1]=[CH:2][CH2:3][CH2:4][CH:5]=[CH2:6].[CH3:7][SiH:8]([Cl:10])[Cl:9]>>[CH2:1]([Si:8]([CH3:7])([Cl:10])[Cl:9])[CH2:2][CH2:3][CH2:4][CH:5]=[CH2:6]5-Hexenylmethyldichlorosilane was prepared by combining 1,5-hexadiene (160 g, 1.95 m), 0.1 g of a platinum complex ##STR1## and methyldichlorosilane (5 g) in a flask equipped with a condenser and a thermometer. The mixture was heated to 40° C. to initiate the reaction. Additional methyldichlorosilane (120 g) was added dropwise to the mixture so that the temperature was kept below 55° C. The product was isolated in 87.6% yield by distillation under reduced pressure (bp 67°-9° C./2 mm Hg).
