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.

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.
摘要:
A method is useful for forming a product including a cyclic siloxane compound. The method includes combining an organodihalosilane and a transition metal on cerium (IV) oxide catalyst, in a reactor at a temperature of to form the product.
