A main object of the present invention is to provide an asymmetric type BF 3 complex which is useful as a solvent for a liquid electrolyte for electrochemical device, in which the liquid electrolyte has a wide potential window and is particularly excellent in oxidation resistance. To attain the object, the present invention provides an asymmetric type BF 3 complex represented by the following general formula (1):
(in the general formula (1), each of R 1 and R 2 is an alkyl group having 1 to 6 carbon atoms and may be the same or different, and R 1 and R 2 may be branched or may form a ring). |
