  • Chelating carbene ligand precursors and their use in the synthesis of metathesis catalysts
    Patent number: 9504997
    Abstract: Chelating ligand precursors for the preparation of olefin methathesis catalysts are disclosed. The resulting catalysts are air stable monomeric species capable of promoting various methathesis reactions efficiently, which can be recovered from the reaction mixture and reused. Internal olefin compounds, specifically beta-substituted styrenes, are used as ligand precursors. Compared to terminal olefin compounds such as unsubstituted styrenes, the beta-substituted styrenes are easier and less costly to prepare, and more stable since they are less prone to spontaneous polymerization. Methods of preparing chelating-carbene methathesis catalysts without the use of CuCl are disclosed. This eliminates the need for CuCl by replacing it with organic acids, mineral acids, mild oxidants or even water, resulting in high yields of Hoveyda-type methathesis catalysts.

  • Copper-indium-gallium-chalcogenide nanoparticle precursors for thin-film solar cells
    Patent number: 9466743
    Abstract: Nanoparticles containing IUPAC group 11 ions, group 13 ions and sulfur ions are synthesized by adding metal salts and an alkanethiol in an organic solvent and promoting the reaction by applying heat. Nanoparticles are formed at temperatures as low as 200° C. The nanoparticles may be thermally annealed for a certain amount of time at a temperature lower than the reaction temperature (usually ˜40° C. lower) to improve the topology and narrow the size distribution. After the reaction is complete, the nanoparticles may be isolated by the addition of a non-solvent and re-dispersed in organic solvents including toluene, chloroform and hexane to form a nanoparticle ink. Additives may be incorporated in the reaction solution to tailor the final ink viscosity.
