The present invention is concerned with a nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing a compound represented by the following general formula (X), in which a polar group (X) is bound to a phosphorus atom (P), and capable of improving electrochemical characteristics in a broad temperature range; an energy storage device using the same; and a novel compound.
In the formula, R

Abstract The reactions of trivalentphosphorusesters, including trialkylphosphites, dialkyl phosphonites, and alkyl phosphinites, with 3-halo- and 3,4-dihalo-furan-2,5-diones has been shown to lead to the formation of novel phosphorus ylides possessing additional phosphoryl-containing groups. For the reaction of 3,4-dihalo-furan-2,5-diones with trialkylphosphites, the products are trialkoxyphosphonium
