Reaction Conditions

Reaction Steps

A 2-L flask equipped with magnetic stirring, pot thermometer, addition funnel and condenser was charged with a mixture of 1455 g (2.05 mol) containing approximately 46% (dichlorosilylmethyl)trichlorosilane and 54% bis(trichlorosilyl)methane [molar ratio 1:1]. To the addition funnel were added 186 g (2.05 mol) of methallyl chloride. The reaction mixture was heated to 110° C. and 20 g of the olefin and 0.5 mL of a 5% solution of chloroplatinic acid in tetrahydrofuran were added to the reaction mixture to initiate the reaction. The remainder of the olefin was added to the reaction mixture at an appropriate rate to maintain the reaction temperature between 110 and 120° C. After completion of the olefin addition, the reaction mixture was heated to 130° C. for an additional 3 hours. Distillation of the product directly from the reaction mixture yielded 412 g (60%) of the title dipodal silane, bp 89-91° C./0.4 mm Hg, density @ 20° C. 1.380.
