  • Selective 1,2-hydrosilylation of terminally unsaturated 1,3-dienes using iron catalysts
    Patent number: 9890182
    Abstract: The present invention is directed to a selective and efficient process for the hydrosilylation of compounds containing terminally unsaturated 1,3-dienes using iron-based hydrosilylation catalysts. The resulting 1,2-addition products are useful as precursors for various silicone materials or silane- or silyl/silicone-functionalized polyolefins.
    Type: Grant
    Filed: May 6, 2014
    Date of Patent: February 13, 2018
    Assignees: MOMENTIVE PERFORMANCE MATERIALS INC., PRINCETON UNIVERSITY
    Inventors: Crisita Carmen Hojilla Atienza, Aroop Kumar Roy, Paul J. Chirik, Keith J. Weller, Johannes G. P. Delis, Tianning Diao

  • Saturated and unsaturated silahydrocarbons via iron and cobalt pyridine diimine catalyzed olefin silylation
    Patent number: 9371339
    Abstract: The present invention relates to processes for the synthesis of saturated and unsaturated silahydrocarbons using iron-containing or cobalt-containing catalysts. The processes of the invention can produce tetraalkylsilanes, phenyltrialkylsilanes, substituted phenyltrialkylsilanes and their mixtures, which are useful as lubricants and hydraulic fluids, as well as alkyl alkenylsilanes, phenyl alkenylsilanes and substituted phenyl alkenylsilanes and their mixtures, which are useful in the synthesis of saturated silahydrocarbons and other organofunctional silanes.
