[Problem] 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.
[Means for Solution] 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 R
1
represents a —COCO— group, a S═O group or a S(═O)
2
group, R
2
represents 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 R
2
may be each substituted with a halogen atom and that R
2
does not represent an aryl group when R
1
represents a —COCO— group.
