  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.

  日期：——

  perfluorobutyl iodide-assisted transition-metal-free cyanomethylation of azoles and phenols with acetonitrile in the presence of NaH has been developed. The reaction proceeded smoothly under mild reaction conditions to give the cyanomethylated products in moderate to high yields. A mechanism involving the cyanomethyl radical through C–H bond cleavage in acetonitrile was proposed.
