权利人:UMICORE AG & CO KG
摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

摘要:The invention provides synthetic methods for the preparation of cantharidin and analogs thereof. In one aspect, the invention provides an improved Diels-Alder cycloaddition to generate a key intermediate en route to cantharidin and analogs thereof. In certain embodiments, the new Diels-Alder reaction involves reacting Compound (2) in the presence of furan, and in the absence of acid or increased pressure, in an aprotic polar solvent with slight warming, to yield Compound (1) in favorable yield and exo-endo ratio. In another aspect, the invention also provides a new Diels-Alder reaction between compounds of Formula (III) and furan to yield compounds of Formula (IV), which can then be transformed into cantharidin or analogs thereof. In yet another aspect, the invention describes a new palladium-mediated carbonylation providing another key intermediate en route to cantharidin and analogs thereof. In addition to synthetic methods, present invention also provides compounds (i.e., intermediates) useful in the synthesis of cantharidin and analogs thereof. Compounds provided herein may have biological activity, and therefore may be used in the treatment of diseases or conditions (e.g., infectious diseases and skin conditions).

摘要:A one-pot synthesis of Nb 5+ -doped TiO 2 nanoparticles (NPs) with low cost and high efficiency for dye sensitized solar cells (DSSCs) is disclosed in the present invention. The Nb 5+ -doped TiO 2 NPs with Nb dopants of 0Ëœ5 mol % are prepared by directly mixing TiO 2 slurry with Nb 2 O 5 gel obtained by UV treatment of a mixture of NbCl 5 powder, ethanol and water in a certain ratio, following by heat treatment without using hydrothermal method. The as-prepared NPs exhibit well-crystallized pure anatase TiO 2 phase with uniform particle distribution. The incorporation of Nb 5+ leads to a stronger and broader light absorption in visible light range and a decrease of band gap with increasing Nb dopant content, which enhances the efficiencies of light-harvesting and electron injection and suppresses the charge recombination. The present method provides a simple and cost-effective mass-production route to synthesize n-type metallic ion doped TiO 2 nanoparticles as excellent photoanode materials.
