Abstract
4-(dialkylchlorosilyl)butyronitriles are prepared by high yield by reacting a mixture of technical grade allyl cyanide with dialkylchlorosilanes in the presence of a catalyst of transition group 8 of the Periodic Table of the Elements, wherein the reaction is conducted such that a stoichiometric excess of the dialkylchlorosilane is present together with the catalyst in the reaction mixture, into which the allyl cyanide is metered.

-8. (canceled)
A method for preparing 4-(dialkylchlorosilyl)butyronitriles, comprising:
- reacting a mixture of technical grade allyl cyanide comprises 100 parts by weight allyl cyanide and 0.01 to 5 parts by weight crotonitrile, with dialkylchlorosilanes in the presence of a catalyst of transition group 8 of the Periodic Table of the Elements, wherein the reaction is conducted such that a stoichiometric excess of the dialkylchlorosilane is present in a reaction mixture with the catalyst, and the technical grade allyl cyanide is metered into the reaction mixture and wherein the alkyl radicals in the dialkylchlorosilane are alkyl radicals having 1 to 6 carbon atoms.
