Abstract
A process produces a C- to C-alkyltrialkoxysilane by hydrosilylation, wherein alkoxy represents methoxy, ethoxy or propoxy. Initially, a mixture is charged of at least one hydroalkoxysilane from the group of hydrotrialkoxysilane, hydroalkyldialkoxysilane, and hydrodialkylalkoxysilane, and a Pt catalyst. The mixture is then heated to a temperature of 30° C. to 60° C. Subsequently, with mixing, an omega-unsaturated or mono-unsaturated C- to C-hydrocarbon, at least one carboxylic acid and at least one alcohol as cocatalysts are added to the mixture. The mixture is then reacted and subsequently worked up to obtain the product.
