  • Calixarene-bound iridium-containing metal colloids
    Patent number: 9295983
    Abstract: The invention provides complexes in which a calixarene-related compound is coordinated to an iridium-containing metal colloid. The complexes can be immobilized on a substrate. The complexes of the invention are useful as tunable and highly robust isolated metal colloids that find use in binding of molecules and catalysis of chemical reactions.

  • Method for producing polycarbonate polyols by the immortal polymerization of cyclic carbonates
    Patent number: 9260562
    Abstract: The invention relates to a process for the preparation of polycarbonate polyols, characterized in that cyclic carbonates are polymerized in the presence of DMC catalysts and chain-transfer agents consisting of polyether carbonate polyols.

  • Methods of Activating Metal Complexes for Catalysts
    Publication number: 20140121427
    Abstract: The present invention is directed to the activation of metal carbonyl clusters by an oxidative agent to prepare a stable metal cluster catalyst exhibiting catalytic rate enhancement. The activation comprises, for example, using oxygen for decarbonylation of carbonyl ligands and changing the oxidation state of the other ligands. In one aspect, treatment of the metal cluster catalyst under oxidative conditions in a flow reactor leads to removal of CO ligands and oxidation of bound calixarene phosphine ligands, and results in a stable activated open metal cluster that is more active for ethylene hydrogenation catalysis. The resulting metal cluster contains coordinatively unsaturated sites comprising carbonyl vacancies. In one aspect, the resulting activated open metal cluster can be used as a catalyst in a variety of chemical transformations.
