标题:The Effect Of Substitution On The Utility Of Piperidines And octahydroindoles For Reversible Hydrogen Storage
摘要:替代哌啶和八氢吲哚在可逆有机储氢液方面,作为氢燃料电池的实用性进行了比较.理论高斯计算表明哪些结构特征可能会降低脱氢焓.实验结果显示,将电子供体或共轭取代基连接到哌啶环上大大提高了催化脱氢速率,其中4-氨基哌啶和哌啶-4-甲酰胺的速率最高.观测到了一些不希望的副反应,例如在4-二甲氨基哌啶脱氢过程中发生的烷基转移反应,4-烷氧基和4-氨基吲哚氢化和/或随后脱氢过程中发生的c-O和c-N断裂反应,以及4-氨基吡啶氢化过程中发生的歧化反应.

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.

标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
发明人：MAJANO GERARDO J; FALKOWSKI JOSEPH M

摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.
