  • Functionalized silicon compounds
    Publication number: 20100063310
    Abstract: A process for preparing a functionalized carbo-silicon compound comprising contacting, in the presence of a hydrosilation catalyst and under hydrosilation promoting conditions: a hydrolyzable silicon reactant having at least one Si—H functional group, and a functionalized olefin reactant containing at least one terminal olefin functional group and a tertiary carbon atom to which is bonded a second functional methyl group or functional carbon group characterized by having substantial potential to impede a hydrosilation reaction when otherwise not attached to the tertiary carbon atom.
