The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and increases in internal resistance upon repeated charge/discharge cycles are suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by benzotriazole.

Reactions of a series of 1-aminobenzimidazoles and 1-amino-3-methylbenzimidazolium chlorides with 2,4-pentanedione were carried out and pyridazino[1,6-a]benzimidazoles and 2-pyrazolylanilines were generated. The product ratios of these compounds remarkably depended on the reaction conditions and on the electronic character of the substituent at the benzene moiety. The possible mechanisms involved in
