Patents by Inventor Takahiro Sawano

Takahiro Sawano 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).

  • Patent number: 11673125
    Abstract: Surface hydroxyl groups on porous and nonporous metal oxides, such as silica gel and alumina, were metalated with catalyst precursors, such as complexes of earth abundant metals (e.g., Fe, Co, Cr, Ni, Cu, Mn and Mg). The metalated metal oxide catalysts provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of organic transformations. The catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
    Type: Grant
    Filed: August 18, 2017
    Date of Patent: June 13, 2023
    Assignee: The University of Chicago
    Inventors: Wenbin Lin, Kuntal Manna, Pengfei Ji, Takahiro Sawano, Zekai Lin

  • Patent number: 10118169
    Abstract: Metal-organic framework (MOFs) compositions based on chiral phosphine-, chiral oxazoline-, chiral pyridine-, and chiral diene-derived organic bridging ligands were synthesized and then post-synthetically metalated with metal precursors such as Ru and Rh complexes. The metal complexes could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations, including the addition of arylboronic acids to ?,?-unsaturated ketones and alkimines, the hydrogenation of substituted alkene and carbonyl compounds, and cyclization reactions. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
