The development of an efficient and sustainable synthetic route for formaldehyde production from renewable feedstock, especially in combination with a subsequent transformation to straightforwardly construct valuable chemicals, is highly desirable. Herein, we report a novel manganese-catalyzed dehydrogenativecyclization of methanol as a formaldehyde surrogate with a variety of dinucleophiles for facile
report a TEMPO‐mediated oxidativecopper‐catalyzed synthesis of N‐(fluoroalkyl)imidazolones via the radical addition of imidazoles with iodofluoroacetate. A possible key intermediate involving TEMPO was observed by ESI‐MS. We also found that aerobicoxidation conditions were effective for the transformation in the presence of a copper catalyst, enabling access to a number of N‐(fluoroalkyl)imidazolones
base‐free N‐alkylation and thioketonization of azoles. Excellent functional group tolerance and high synthetic efficiency proved particularly advantageous for the rapid assembly of a large array of pharmaceutically‐oriented azole thiones, many of which contain synthetically and biologically useful functional groups. The direct transformation of drug molecules (such as Ketoconazole, Econazole, and Fluconazole)

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.
