  • Non-precious metal-based hyrdosilylation catalysts exhibiting improved selectivity
    Patent number: 11052383
    Abstract: Disclosed herein is the use of manganese, iron, cobalt, or nickel complexes containing tridentate pyridine di-imine ligands as hydrosilylation catalysts. These complexes are effective for efficiently catalyzing hydrosilylation reactions, as well as offering improved selectivity and yield over existing catalyst systems.
    Type: Grant
    Filed: September 26, 2017
    Date of Patent: July 6, 2021
    Assignees: MOMENTIVE PERFORMANCE MATERIALS INC., PRINCETON UNIVERSITY
    Inventors: Keith James Weller, Crista Carmen H. Atienza, Julie Boyer, Paul Chirik, Johannes G. P. Delis, Kenrick Lewis, Susan A. Nye
