标题:用tempo合并染料敏化的tio 2的可见光光催化:醇的选择性好氧氧化
摘要:当氧化剂是分子氧(o 2)并且反应在环境条件下进行时,很难将醇选择性氧化为醛或酮.为了应对这些挑战,开发了可见光光催化技术,以使o 2可以在室温下用于醇的选择性氧化.在该方案中,将曙红y(一种有机染料)与tio 2连接捕获可见光,从而导致相应的光催化过程.更重要的是,这些光催化过程可以与tempo的氧化还原催化循环巧妙地合并,从而在可见光照射下诱导醇的氧化.这项工作表明可见光光催化和tempo催化的合并具有巨大的潜力执行具有挑战性的氧化转化.

权利人:SANDOZ AG
摘要:The present invention relates to processes comprising a combined racemization and stereoselective reductive amination step in which an aldehyde compound of formula (I) is contacted with an (R)-selective ω-transaminase or an (S)-selective ω-transaminase to racemize the compound of formula (I) and obtain an amine compound of formula (II). These processes are useful for the preparation of precursors of pharmaceutically active agents such as brivaracetam and pregabalin.

发明人：MATSUMURA YASUO; SUYAMA KAZUHARU; INOMATA YOSHIHISA
权利人:NIPPON PETROCHEMICALS CO LTD
摘要:A method for producing cyclopentadienes which comprises the step of cyclodehydration of an unsaturated carbonyl compound having a specific chemical structure in a vapor phase in the presence of a specific solid acid catalyst. The cyclopentadienes of the invention can be produced in a high yield from inexpensive starting materials through a simplified reaction process and are useful as intermediate compounds for organic synthesis.

摘要:Novel tetracyanoanthraquinodimethane polymers and use thereof. The problem addressed was that of providing novel polymers which are preparable with a low level of complexity, with the possibility of controlled influence on the physicochemical properties thereof within wide limits in the course of synthesis, and which are usable as active media in electrical charge storage elements for high storage capacity, long lifetime and stable charging/discharging plateaus. Tetracyanoanthraquinodimethane polymers consisting of an oligomeric or polymeric compound of the general formula I have been found.
