1) Dow Corning Corporation, Midland, Mich. Some silicon hydrides add to the double bond of olefinic compounds in the presence of platinic chloride, platinized carbon, platinum black, ruthenium chloride and iridium. The addition reaction is exothermic and in many cases very rapid at temperatures from below room temperature to about 100°. Pentene-1 and pentene-2 both form n-pentylsilanes under these conditions. Only in the presence of a very active catalyst would cyclohexene react. Silicon hydrides useful in this reaction include trichlorosilane, methyldichlorosilane, dimethylchlorosilane, phenyldichlorosilane, 1,1,3,3-tetramethyldisiloxane. diethoxymethylsilane and others. A wide variety of olefinic compounds are reactive. In some cases allyl acetate and other allyl compounds as well as isopropenyl acetate form propylene.
