  • Asymmetric syntheses
    Patent number: 5491266
    Abstract: This invention relates to asymmetric syntheses in which a prochiral or chiral compound is contacted in the presence of an optically active metal-ligand complex catalyst to produce an optically active product.
    Type: Grant
    Filed: June 20, 1994
    Date of Patent: February 13, 1996
    Assignee: Union Carbide Chemicals & Plastics Technology Corporation
    Inventors: James E. Babin, Gregory T. Whiteker
  • Process for stabilizing phosphite ligands in hydroformylation reaction mixtures
    Patent number: 5364950
    Abstract: This invention provides a process for stabilizing a phosphite ligand against degradation in a homogeneous reaction mixture containing a Group VIII transition metal catalyst and the phosphite ligand, said process comprising adding to the reaction mixture an epoxide in an amount from 0.001 to 5 weight percent based on the total weight of the reaction mixture to reduce the degradation of the ligand.
    Type: Grant
    Filed: September 29, 1992
