  • Patent number: 9592497
    Abstract: The present disclosure provides a process for the mono-reduction of one or more imide moieties in a compound comprising contacting the compound with hydrogen gas and a catalyst comprising a transition metal hydride in the presence of a base, under conditions for the mono-reduction of the one or more imide moieties to form a compound comprising one or more hydroxy amides.
    Type: Grant
    Filed: June 17, 2010
    Date of Patent: March 14, 2017
    Assignee: THE GOVERNORS OF THE UNIVERSITY OF ALBERTA
    Inventors: Steven H. Bergens, Satoshi Takebayashi
  • Publication number: 20160175829
    Abstract: The present application provides a composite material and system for use in a heterogeneous flow reactor, which can include: a catalytic polymeric framework comprising catalyst-containing monomeric units each separated by at least one non-catalyst-containing monomeric unit; and a solid support material, wherein the catalytic polymeric framework is covalently or non-covalently immobilized on or in the support material. Each catalyst-containing monomeric subunit in the polymeric framework comprises a transition metal bound to a catalyst ligand. Also provided are methods of manufacture and use of the catalyst system and composite material.
