  • Patent number: 7820843
    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.

  • Patent number: 7001536
    Abstract: Organic light emitting devices are described wherein the emissive layer comprises a host material containing an emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including cyclometallated platinum, iridium and osmium complexes. The organic light emitting devices optionally contain an exciton blocking layer. Furthermore, improved electroluminescent efficiency in organic light emitting devices is obtained with an emitter layer comprising organometallic complexes of transition metals of formula L2MX, wherein L and X are distinct bidentate ligands. Compounds of this formula can be synthesized more facilely than in previous approaches and synthetic options allow insertion of fluorescent molecules into a phosphorescent complex, ligands to fine tune the color of emission, and ligands to trap carriers.

  • Patent number: 6255324
    Abstract: 5′-substituted, 4′,5′-dihydropsoralen compounds (5) bearing tertiary amines (and salts thereof), quaternary ammonium moieties or organomercurial moieties are described. Also described are 2-substituted mercurimethyl-2-3-dihydro-benzofurans of forumla (7): Also reported are versatile direct syntheses through a hitherto unknown compounds such as 3-R-4,8-dimethyl-4′,5′-dihydro-5′-bromomethylpsoralen or a 3-R-4,8-dimethyl-4′, 5′-dihydro-5′-iodomethylpsoralen to prepare a structurally diverse array of partially reduced psoralens and benzofurans. The presence of a permanent ammonium charge in these psoralens precludes membrane passage and the mono-unsaturation precludes the cross-linking of nuclear DNA, thereby minimizing the mutagenic/carcinogenic side effects long associated with psoralen-derived therapies.
