  • Catalyst compounds
    Patent number: 9212199
    Abstract: The present invention relates to an iridium-based catalyst compound for hydrogenating reducible moieties, especially imines and iminiums, the catalyst compounds being defined by the formulas: where ring B is either itself polycyclic, or ring B together with R is polycyclic. The catalysts of the invention are particularly effective in reductive amination procedures 10 which involve the in situ generation of the imine or iminium under reductive hydrogenative conditions.
    Type: Grant
    Filed: April 15, 2013
    Date of Patent: December 15, 2015
    Assignee: The University of Liverpool
    Inventors: Dinesh Talwar, Weijun Tang, Chao Wang, Barbara Villa Marcos, Jianliang Xiao

  • CATALYST COMPOUNDS
    Publication number: 20150073165
    Abstract: The present invention relates to an iridium-based catalyst compound for hydrogenating reducible moieties, especially imines and iminiums, the catalyst compounds being defined by the formula: (Formula (I)) where ring B is a conjugated ring system with one or more substituents. The catalysts of the invention are particularly effective in reductive amination procedures which involve the in situ generation of the imine or iminium under reductive hydrogenative conditions.
