Continuous processing of liquid/liquid synthesis and microreaction technology are shown to reduce the cost of process development and manufacturing of activepharmaceuticalingredients and other functional molecules on a commercial scale. Combinatorial synthesis systems for continuous chemistry are introduced, and their applications are described. Reactions within these systems scale seamlessly in

liquids exhibit excellent hydrolytic stability, low viscosity and high electrochemical and thermal stability. Organic and inorganic salts with FAP anions possess high electrochemical stability and conductivity that makes them attractive for application in several electrochemical devices (Li-ion batteries, super-capacitors, etc.). The possible application of H[(RF)3PF3] (HFAP), (RF)2P(O)(OH) and (RF)P(O)(OH)2

of this species up to −40 °C is of advantage, particularly in comparison to its smaller congener LiCF3. The usual production of LiC2F5, however, from gaseous HC2F5 or IC2F5 and strong bases requires specially designed apparatuses, which severely impeded its value as a laboratory reagent. In this contribution we communicate an alternative gas‐free and highly efficient protocol for the synthesis of LiC2F5
已经建立了五氟乙基锂LiC 2 F 5作为一种高效且通用的试剂,用于将五氟乙基单元转移到许多亲电试剂中。在此,该物质在最高-40°C的温度下具有稳定性,特别是与其较小的同类LiCF 3相比。然而,由气态HC 2 F 5或IC 2 F 5和强碱生产LiC 2 F 5,通常需要特殊设计的设备,这严重地削弱了其作为实验室试剂的价值。在这项贡献中,我们交流了用于合成LiC 2的另一种无气体且高效的方案˚F 5从已经商业化锡盐[PPH 4 ] [Sn的(C 2 ˚F 5)5 ]。[Sn(C 2 F 5)5 ] -阴离子不仅代表结构表征的高价五烷基锡酸酯的第一个实例,而且还用作合成均四(五氟乙基)锡烷,Sn(C 2 F 5)的前体。4。后者与正丁基锂的反应提供了对LiC 2 F 5生成机理的深入了解。
