Anil Guram has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Substituted aminomethylphosphines, compositions and coordination complexes of same, their synthesis and processes using same
    Patent number: 6177528
    Abstract: Novel aminomethylphosphine ligands have particular substituents on the central carbon atom. Such ligands form coordination complexes that may be catalysts for the polymerization of monomers or other catalytic induced reactions.
    Type: Grant
    Filed: December 14, 1999
    Date of Patent: January 23, 2001
    Assignee: Symyx Technologies, Inc.
    Inventors: Anne Marie LaPointe, Anil Guram, Timothy S. Powers, Bernd Jandeleit, Thomas Boussie, Cheryl Lund
  • Catalyst ligands, catalyst compositions, catalyst metal complexes and processes for cross-coupling aromatic boron compounds with aromatic halogens or perfluoroalkylsulfonates
    Patent number: 6124476
    Abstract: The present invention discloses new organic compounds (e.g., ligands), their metal complexes and compositions using those compounds. The invention also relates to the field of catalysis. In particular, this invention relates to new compounds which when combined with suitable metals or metal precursor compounds provide useful catalysts for various bond-forming reactions, including Suzuki cross-coupling reactions. The invention also relates to performing Suzuki cross coupling reactions with unreactive aryl-chlorides.

  • Preparation of arylamines
    Patent number: 5576460
    Abstract: A method of preparing an arylamine compound includes reacting a metal amide comprising a metal selected from the group consisting of tin, boron, zinc, magnesium, indium and silicon, with an aromatic compound comprising an activated substituent in the presence of a transition metal catalyst to form an arylamine. The method is useful in preparing mixtures of arylamines for use in screening for pharmaceutical and biological activity and in preparing poly(anilines).
