  • Publication number: 20220145038
    Abstract: A method for modifying a cellular polymer foam with apparent porosity, which includes providing a cellular polymer foam with apparent porosity, placing the cellular polymer foam in contact with at least one compound in order to obtain a cellular polymer foam including on the surface thereof an intermediate phase formed from the compound having at least one catechol unit. The foam may be used as a catalyst substrate.

  • Publication number: 20190264000
    Abstract: Disclosed is a reduction kit including a reducing compound and an open-cell polymer foam, the surface of which includes a polymer having a catechol unit. Also disclosed is a reducing composition including an open-cell foam, the surface of which includes a polymer having a catechol unit, the foam being functionalized by a reducing compound. The use of the kit or composition as a reagent in reduction reactions is also disclosed.

  • Patent number: 7884223
    Abstract: The invention relates to an enantiomerically enriched chiral compound comprising a transition metal M, which comprises four, five or six coordinating groups of which at least one pair is linked together to form a bidentate ligand, in which M is directly bound via one single ?-bond to a carbon atom of an optionally substituted and/or optionally fused (hetero)aromatic ring of said bidentate ligand and in which M is directly bound to a nitrogen atom of a primary or secondary amino group of said bidentate ligand, thereby forming a metallacycle between said bidentate ligand and the metal M, said metal M being selected from the metals of groups 8 and 9 of the Periodic Table of the Elements, in particular iron, ruthenium, osmium, cobalt, rhodium, or iridium. The chiral compound can be used as a catalyst, preferably in an asymmetric transfer hydrogenation process.
