专利号:US-8987504-B2 优先权日:2010-06-18 标题 :Aminohydroxylation of alkenes 发明人:MEE SIMON PETER HAROLD; LUXENBURGER ANDREAS; HARRIS LAWRENCE DANIEL 权利人:MEE SIMON PETER HAROLD; LUXENBURGER ANDREAS; HARRIS LAWRENCE DANIEL; VICTORIA LINK LTD 摘要:The invention relates to a process for the aminohydroxylation of alkenes using N-oxycarbamate reagents, e.g. N-acyloxycarbamate, N-alkyloxycarbonyloxycarbamate and N-aralkoxycarbonyloxycarbamate reagents. The invention particularly relates to an intermolecular aminohydroxylation reaction that can be carried out in the absence of added base. The invention also relates to novel N-oxycarbamate reagents that are stable crystalline materials. The process of the invention is useful in the synthesis of compounds having a vicinal amino alcohol moiety, such as biologically active compounds.
专利号:WO-2013044080-A1 优先权日:2011-09-22 标 题 :Electrochemical synthesis of elongated noble metal nanoparticles, such as nanowires and nanorods, on high-surface area carbon supports 发明人:ADZIC RADOSLAV; BIZNAKOV STOYAN; VUKMIROVIC MIOMIR 权利人:BROOKHAVEN SCIENCE ASS LLC; ADZIC RADOSLAV; BIZNAKOV STOYAN; VUKMIROVIC MIOMIR 摘要:Elongated noble-metal nanoparticles and methods for their manufacture are disclosed. The method involves the formation of a plurality of elongated noble-metal nanoparticles by electrochemical deposition of the noble metal on a high surface area carbon support, such as carbon nanoparticles. Prior to electrochemical deposition, the carbon support may be functionalized by oxidation, thus making the manufacturing process simple and cost-effective. The generated elongated nanoparticles are covalently bound to the carbon support and can be used directly in electrocatalysis. The process provides elongated noble-metal nanoparticles with high catalytic activities and improved durability in combination with high catalyst utilization since the nanoparticles are deposited and covalently bound to the carbon support in their final position and will not change in forming an electrode assembly.
