    摘要: Novel diaralkyldichlorosilanes of the general formula (I)
    (wherein R 1 and R 2 each represent hydrogen or C 1 to C 4 alkyl, R' and R 4 each represent C 1 to C 4 alkyl, p and q are 0 to 3; provided that R 1 and R 2 are not hydrogen when p and q are 0) can be made from dichlorosilane and the corresponding styrene compounds and are useful as monomers for producing polysiloxanes and as intermediates for synthesizing organosilicon compounds.

    摘要: An acryloxy or methacryloxy group-containing organosilicon compound of the formula

    (wherein R 1 is a substituted or unsubstituted monovalent hydrocarbon group of 1 to 10 carbon atoms, R 2 is a hydrogen atom or a methyl group, R 3 is an unsubstituted divalent hydrocarbon group of 1 to 18 carbon atoms, X is a halogen atom and n is an integer of 1, 2 or 3) is prepared by subjecting a hydrohalosilane compound of the formula

             HSiX n R 1 3-n      (1)

    and an alkenyl group-containing (meth)acrylate compound of the formula

    to a hydrosilylation reaction in the presence of an acid amide compound and a platinum catalyst. This method is able to suppress, in the industrial scale production of (meth)acryloyloxy group-containing organosilicon compounds, propagation reactions by which the starting (meth)acrylate compound self-polymerizes.

    摘要: The invention relates to a method for producing 4-(dialkylchlorosilyl)-butyronitriles by reacting a mixture of allyl cyanide T with technical purity, with dialkylchlorosilanes in the presence of a catalyst from the eighth subgroup of the periodic table of the elements, the reaction being carried out such that in the presence of the catalyst, there is a stoichiometric excess of the introduced dialkylchlorosilane in the reaction mixture, and the allyl cyanide T is added thereto.
