标题:Carbon Dioxide Mediated,Reversible Chemical Hydrogen Storage Using A Pd Nanocatalyst Supported On Mesoporous Graphitic Carbon Nitride
摘要:可逆的二氧化碳介导的化学氢存储首次使用负载在中孔石墨相氮化碳(pd/mpg-C3N4)上的异质pd催化剂进行示范.研究发现,Pd纳米颗粒均匀分散在mpg-C3N4上,平均尺寸为1.7纳米,且没有任何团聚现象.其在常温下对甲酸的脱氢反应表现出极佳的活性,周转频率达到144 H−1,甚至在没有外部碱的情况下亦然.初步的dft研究表明,Mpg-C3N4载体上的碱性位点在无表面活性剂的情况下,对稳定还原态的pd纳米颗粒以及通过去质子化甲酸来启动氢气释放起到协同作用.这些潜在相互作用通过x射线吸收近边结构(xanes)得到了进一步确认.除了脱氢反应外,Pd/mpg-C3N4还证明能够催化通过co2氢化再生甲酸.进一步阐明了co2氢化的主要影响因素,以提高所需甲酸的产量和选择性.

权利人:UNIV TALCA
摘要:Described herein is a new asymmetric synthesis of imines to obtain β-carboline derivatives useful as key intermediate compounds for the synthesis of phosphodiesterase inhibitors using a new process with palladium or ruthenium hydride and/or nickel boride to reduce chiral intermediates. The use of chloroformate chiral auxiliaries is further described for the reduction and asymmetric hydrogenation of imines to obtain β-carboline derivatives and intermediate compounds used in the preparation thereof.

标题 :Monomer for synthesis of RNA, method for producing same, and method for producing RNA
发明人：KATAOKA MASANORI
权利人:UNIV KOCHI
摘要:The objective of the present invention is to provide a monomer for RNA synthesis which can be efficiently produced and therefore by which the producing cost of RNA can be remarkably decreased, and a method for efficiently producing the monomer in a small number of steps. In addition, the objective of the present invention is also to provide a method by which RNA can be efficiently produced even when a approximately stoichiometry amount of the monomer for RNA synthesis is used. The monomer for RNA synthesis according to the present invention is represented by the following formula (I) or (I′): n nwherein R 1 is a protective group of the hydroxy group and R 2 is an alkyl group or the like.
