A method for the C-N coupling of imidazoles based on electrooxidative C-H functionalization of aromatic and benzylic compounds has been developed. The key to the success is the formation of protected imidazolium ions as initial products, avoiding overoxidation. Deprotection under nonoxidative conditions affords N-substituted imidazoles. Various functional groups are compatible with the present transformation

Heteroaryl sulfonyl compounds and compositions that have a CDK2 Recognition Moiety bound to an electrophile for the selective covalent modification of CDK2 to treat CDK2-mediated disorders are described.
An effective method was explored for the selective synthesis of sulfonamides and sulfenamides using sodium sulfinates and amines as starting materials. This method offers mild reaction conditions, a broad substrate scope, high efficiency, and readily accessible materials, making it suitable and an alternative strategy for the preparation of a variety of biologically or pharmaceutically active compounds

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.
