Visible-Light-Driven Silver-Catalyzed One-Pot Approach: A Selective Synthesis of Diaryl Sulfoxides and Diaryl Sulfones

An efficient one-pot approach for the synthesis of diaryl sulfoxides and diaryl sulfones using aryl thiols and aryl diazonium salts was developed. The use of a visible-light-driven silver catalysis and the subsequent singlet-oxygen-induced oxidation enabled selective synthesis of sulfoxides and sulfones in the absence of a photocatalyst. The reactions were carried out under mild reaction conditions; the desired products were obtained under air atmosphere at room temperature.

The synthesis of diarylsulfones with simple arenes and K2S2O8 through double C-S bond formation

An unprecedented double C-S bond formation method has been developed to prepare both symmetric and unsymmetric diarylsulfones with simple arenes in a single step. This represents the first example that K2S2O8 can be employed as a highly effective sulfonating agent to synthesize diarylsulfones. The reaction demonstrates excellent reactivity, good functional group tolerance and high yields.

Copper-mediated cascade synthesis of diaryl sulfones via the sandmeyer reaction

A convenient and efficient method for the copper-mediated cascade synthesis of diaryl sulfones via the Sandmeyer reaction has been developed. The protocol uses readily available aryl amines and arylsulfinic acids as the starting materials, isoamyl nitrite as the diazotizating reagent of the aryl amines, and the method shows mild reaction conditions and high tolerance towards various functional groups in the substrates.

Indium(III)-catalysed aryl sulfonylation reactions

A rapid, high yielding and regioselective process has been developed for the synthesis of biaryl sulfones via sulfonylation reactions catalysed by indium(III) chloride.

Preparation process of fluorine substituted aromatic compound

A preparation process of a fluorine substituted aromatic compound comprising reacting an alkali metal or alkali earth metal salt of an aromatic compound having a hydroxy group with an organic fluorinating agent is disclosed. As a representative fluorinating agent, a bis-dialkylamino-difluoromethane compound, for example, 2,2′-difluoro-1,3-dimethylimidazolidine, is exemplified. According to the process, an industrially useful fluorinated aromatic compound, for example, a fluorobenzene, a fluorine substituted benzophenone, a fluorine substituted diarylsulfone can be prepared with ease in economy without specific equipment.

Tetramethylammonium hydrogendifluoride: A convenient source of nucleophilic fluoride

Tetramethylammonium hydrogendifluoride (TMAHF2) acts as an effective fluoride source for the selective fluorination in high yields of various chloro and nitroaromatics via halogen exchange (halex) and fluorodenitration.

Methylhexamethylenetetramine fluoride dihydrate: A new fluorodenitration reagent

Methylhexamethylenetetramine fluoride dihydrate has been prepared by conventional methods. It is moderately soluble in polar aprotic solvents, and shows good thermal stability, enabling it to be dried. The reagent is capable of converting activated nitroaromatics to the corresponding fluoroaromatics, with a high selectivity to monofluorodenitration being observed with some polysubstituted aromatics.
