  • Process for the conversion of cyclic amines into lactams
    Patent number: 8212027
    Abstract: Converting cyclic amines to lactams using gold supported catalysts.
    Type: Grant
    Filed: April 27, 2011
    Date of Patent: July 3, 2012
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Lee Keith Woo, Robert J. Angelici
  • Process for the synthesis of .alpha., .beta.-unsaturated esters
    Patent number: 5859268
    Abstract: The present invention provides a process for the synthesis of an .alpha.,.beta.-unsaturated ester from a mono-olefin-ester using Fe(CO).sub.5.
    Type: Grant
    Filed: April 8, 1997
    Date of Patent: January 12, 1999
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Robert J. Angelici, Kuo-Chen Shih
  • Catalyst system comprising a first catalyst system tethered to a supported catalyst
    Patent number: 5789333
    Abstract: The present invention provides new catalyst formats which comprise a supported catalyst tethered to a second and different catalyst by a suitable tethering ligand. A preferred system comprises a heterogeneous supported metal catalyst tethered to a homogeneous catalyst. This combination of homogeneous and heterogeneous catalysts has a sufficient lifetime and unusually high catalytic activity in arene hydrogenations, and potentially many other reactions as well, including, but not limited to hydroformylation, hydrosilation, olefin oxidation, isomerization, hydrocyanation, olefin metathesis, olefin polymerization, carbonylation, enantioselective catalysis and photoduplication. These catalysts are easily separated from the products, and can be reused repeatedly, making these systems very economical.
    Type: Grant
