标题:Synthesis of aromatic amines by reaction of aromatic compounds with ammonia
发明人：DELPESCO THOMAS WAYNE
权利人:DU PONT
摘要:An improved process is provided for producing an aromatic amine from ammonia and an aromatic compound which comprises reacting the aromatic compound with ammonia at a temperature of from about 150 DEG C. to about 500 DEG C. and at a pressure of from about 10 to about 1000 atmospheres in the presence of a conditioned nickel/nickel oxide/zirconium oxide cataloreactant containing an oxide of lanthanum, samarium, holmium, europium, erbium, yttrium, praseodymium, neodymium, terbium, ytterbium, dysprosium or a mixture of any of them.

标 题:Method for the intramolecular energy transfer for the cleavage of labile functional group from biomolecules and the protected biomolecules
发明人：STEINER ULRICH; WOELL DOMINIK
权利人:STEINER ULRICH; UNIV KONSTANZ; WOELL DOMINIK
摘要:The present invention provides a chemical compound and a method for the cleavage of labile functional groups from molecules by the interaction of electromagnetic radiation by the use of the chemical compound. Further, the invention provides a method for the manufacture of DNA chips by spatially addressed light directed nucleotide synthesis on solid substrates. The cleavage of the labile functional group is achieved by intramolecular energy transfer of the excitation energy.

发明人：STEINER ULRICH; WOLL DOMINIK; WALBERT STEFAN
权利人:UNI KONSTANZ
摘要:The present invention provides a method for cleavage of labile functional groups from molecules by the action of electromagnetic radiation, wherein the molecules are contacted with a chemical compound whose triplet state is energetically higher than the triplet state of the labile functional group, and are subsequently exposed to electromagnetic radiation. Further, the invention provides a method for preparing DNA chips by spatially addressed, light-controlled nucleotide synthesis on solid substrates, said method comprising the following steps: a) reacting the unprotected terminal 3′ or 5′ hydroxy group of a nucleoside and/or of a nucleotide arranged on the solid substrate under usual conditions with a photolabile protective group and optionally purifying the reaction product, b) applying a solution, suspension or dispersion of a chemical compound, whose triplet state is energetically higher than the triplet state of the photolabile protective group, to the surface of the carrier, said surface comprising the nucleotides and/or nucleosides modified in step a): c) irradiating, in a spatially selective manner, the surface of the carrier treated in step b) with electromagnetic radiation in the UV/VIS range with simultaneous, spatially selective release of a reactive OH group and subsequently reacting it with a nucleoside and/or nucleotide comprising a 5′ or 3′OH group, said nucleoside and/or nucleotide being further provided with a photolabile functional group. Moreover, the present invention provides a chemical composition comprising a molecule having a labile functional group, as well as a chemical compound whose triplet state is higher than the triplet state of the labile functional group, and it describes the use of the chemical composition for preparing DNA chips.
