  controlling the reaction by TLC monitoring and using ‘dry column’ chromatography. Compound (3) was readily converted to 1,2,3,4-tetrafluoro-5,6-dinitrobenzene (2) by peroxytrifluoroacetic acid and to 3,4,5,6-tetrafluoro-1,2-phenylenediamine (1) by SnCl2/HCl. Compound (1) was shown to be a versatile intermediate for the synthesis of tetrafluoro-benzimidazoles, -triazoles and -quinoxalines. The fungicidal

  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.
