  2-Fluoro-4,4,5,5-tetramethyl-1,3-dioxolane: A compound carrying two independent probes for determining rates of formations of contact and solvent-separated ion pairs

  摘要：

  2-Fluoro-4,4,5,5-tetramethyl-1,3-dioxolane was shown to be a useful compound for independently determining the rate constants of contact ion pair and solvent-separated ion pair formations. The compound was used to determine rate constants for toluene-d(8) and chloroform-d solutions and they were found to be identical for each solution. (C) 1998 Elsevier Science Ltd.

  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.

  stabilization of the original state due to hydrogen-bond formation with the acidic C(2) – H group of the substrate in those solvents. The hydrogen-bond formation is hindered by the steric effects in bulkier solvents than in smaller solvents. The rates of contact ion pair and solvent-separated ion pair formations should be independently determined in 2-fluoro-4,4,5,5-tetramethyl-1,3-dioxolane, but so
