Reactions of dimethyl malonate, diphenyl malonate, methyl cyanoacetate, and malononitrile with 1-chloro-2,4,6-trinitrobenzene or 1-fluoro-2,4,6-trinitrobenzene in the presence of triethylamine in organic solvents gave stable brightly colored crystalline triethylammonium salts of the corresponding 2,4,6-trinitrophenylmalonic acid derivatives.
Copper ion catalyzed carbon-carbon bond forming reaction of N-acyliminium ions with diaryl the method were 2-methoxy-3,4-didehydropiperidines, which were easily prepared through electrochemical oxidation of 1-(p-methoxybenzoyl)piperidine in methanol followed by the conversion of the oxidation product to didehydropiperidine derivative, which was subjected to a chiral Cu(II) catalyzed coupling reaction with diaryl malonates affording diaryl 2-piperidylmalonates. The maximum % ee (ee, enantiomeric excess) was 97% when di-p-chlorophenyl malonate was used as a nucleophile. (c) 2006 Elsevier B.V. All rights reserved.

The present invention provides a nonaqueous electrolytic solution capable of improving electrochemical characteristics in a broad temperature range, such as low-temperature cycle properties and low-temperature discharge properties after high-temperature storage, and provides an energy storage device using the nonaqueous electrolytic solution. The invention includes (1) a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, which comprises from 0.001 to 10% by mass of a compound represented by the following general formula (I), and (2) an energy storage device comprising a positive electrode, a negative electrode, and a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, wherein the nonaqueous electrolytic solution is the nonaqueous electrolytic solution of (1).
