  • Platinum (II) diene complexes with chelating dianionic ligands and their use in hydrosilylation reactions
    Patent number: 10047108
    Abstract: A process for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl hydride with (b) an unsaturated compound in the presence of (c) a platinum based hydrosilylation catalyst comprising a platinum-diene complex with chelating anions. The use of the present catalysts in the process provides silylated products in good yields and allows for using lower platinum loadings than conventional catalysts, reduced cycle times, and may reduce yellowing in the product.
    Type: Grant
    Filed: December 15, 2015
    Date of Patent: August 14, 2018
    Assignee: MOMENTIVE PERFORMANCE MATERIALS INC.
    Inventors: Julie L. Boyer, Aroop K. Roy, David Jenkins, Indraneel Kundu
