Methods for preparing fluorinated sulfides and fluorinated sulfones are described. To prepare a fluorinated sulfides, a sulfur-containing reactant represented by the formula: R1SM or M2S, wherein R1 is a C1 to C10 alkyl or fluoroalkyl, S is sulfur, and M is a cation, is reacted with a fluorinated alkyl compound. A fluorinated sulfone is formed by oxidizing the fluorinated sulfide. The fluorinated sulfones prepared by the methods disclosed herein are particularly useful as electrolyte solvents for electrochemical cells, such as a lithium ion battery, where a high purity solvent is desired.
描述了制备氟硫化物和氟磺酮的方法。要制备氟硫化物,将表示为R1SM或M2S的含硫反应物(其中R1是C1到C10的烷基或氟烷基,S是硫,M是阳离子)与氟化烷基化合物发生反应。通过氧化氟硫化物形成氟磺酮。根据本公开的方法制备的氟磺酮在电化学电池等电化学电池中特别适用作电解质溶剂,其中需要高纯度溶剂。
