  • Unsymmetric bisphosphite
    Patent number: 9556096
    Abstract: An unsymmetric bisphosphite of the formula (1) a process for preparation thereof, a reaction thereof with metals to give mixtures containing complexes of the unsymmetric bisphosphite and the metal, and a use thereof as a catalytically active composition in hydroformylation reactions, where the hydroformylation-active composition contains, as well as the complex of metal and unsymmetric bisphosphite, unbound bisphosphite and at least one further component.
    Type: Grant
    Filed: September 27, 2013
    Date of Patent: January 31, 2017
    Assignee: Evonik Degussa GmbH
    Inventors: Andrea Christiansen, Robert Franke, Dirk Fridag, Dieter Hess, Katrin Marie Dyballa, Bernd Hannebauer
  • Mixtures of constitutionally isomeric bisphosphites
    Patent number: 9499463
    Abstract: The invention relates to mixtures of constitutional isomer bisphosphites of formulae (1a) and (2a), to a method for the production thereof, to the reaction thereof with metals to form mixtures containing complex compounds of the constitutional isomer bisphosphites of formulae (1a) and (2a) and the metal, and to the use thereof as a catalytically active composition in hydroformylation reactions. Said hydroformylactically active compositions comprises, in addition to the complex compounds of metal and the constitutional isomer bisphosphites of formulae (1a) and (2a), non-bound bisphosphites of the constitutional isomer bisphosphites of formulae (1a) and (2a) and at least one additional component.
