Pentafluorophenyloxy compound, and nonaqueous electrolyte solution and lithium secondary battery using same

Abstract

To provide a novel pentafluorophenyloxy compound, a method for producing same, a nonaqueous electrolyte solution capable of forming a lithium secondary battery having excellent battery characteristics such as electrical capacity, cycling property and storage property, and a lithium secondary battery. A pentafluorophenyloxy compound represented by the general formula (I) shown below, a method for producing same, a nonaqueous electrolyte solution containing same and a lithium secondary battery: wherein Rrepresents a —COCO— group, a S═O group or a S(═O)group, Rrepresents an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aryl group or an aralkyl group with the proviso that at least one of the hydrogen atoms of Rmay be each substituted with a halogen atom and that Rdoes not represent an aryl group when Rrepresents a —COCO— group.
