  A lithium sulfur battery comprising an electrolyte solvent which comprises at least one fluorosubstituted compound is described. Preferred fluorosubstituted compounds which are predominantly solvents are notably selected from the group consisting of fluorosubstituted carboxylic acid esters, fluorosubstituted carboxylic acid amides, fluorosubstituted fluorinated ethers, fluorosubstituted carbamates, fluorosubstituted cyclic carbonates, fluorosubstituted acyclic carbonates, fluorosubstituted ethers, perfluoroalkyl phosphoranes, fluorosubstituted phosphites, fluorosubstituted phosphates, fluorosubstituted phosphonates, and fluorosubstituted heterocycles. Monofluoroethylene carbonate, cis-difluoroethylene carbonate, trans-difluoroethylene carbonate, 4,4-difluoroethylene carbonate, trifluoroethylene carbonate, tetrafluoroethylene carbonate, 4-fluoro-4-methyl-1,3-dioxolane-2-one, 4-fluoro-4-ethyl-1,3-dioxolane-2-one, 2,2,2-trifluoroethyl-methyl carbonate, 2,2,2-trifluoroethyl-fluoromethyl carbonate are preferred. The solvent may further comprise a non-fluorinated solvent, e.g., ethylene carbonate, a dialkyl carbonate, or propylene carbonate. Use of such fluorinated compound as additive for such batteries and specific electrolyte solutions.

  of amines has been developed. Mechanistic studies have revealed that the ability of the base to facilitate the desired amination without promoting unwanted side reactions is the guiding factor. By employing lithium bis(trimethylsilyl)amide as a base the resultant deprotonated amines readily react with a range of unactivated fluorobenzene derivatives. This new arylation method is utilized for the simple

  已经开发了一种用于胺类的无过渡金属N芳基化的通用方法。机理研究表明，碱促进所需胺化而不促进不希望的副反应的能力是指导因素。通过使用双（三甲基甲硅烷基）酰胺锂作为碱，所得的去质子化的胺容易与一系列未活化的氟苯衍生物反应。这种新的芳基化方法用于抗抑郁药伏替西汀的简单两步合成。
