- Method for synthesizing sulfone compounds under photocatalysis condition
-
The invention belongs to the technical field of compound preparation, and particularly relates to a method for synthesizing sulfone compounds under a photocatalysis condition. Aromatic hydrazine and sulfinate are used as raw materials, and under the action of alkali and a solvent, a sulfone compound is generated through reaction under the condition of air or oxygen under the illumination of visible light. According to the method disclosed by the invention, aryl hydrazine is used as an arylation reagent, polyacid salt is used as a catalyst or an organic photosensitizer is used as a catalyst, and the sulfones compound can be efficiently synthesized by coupling with sulfinate under the condition of room temperature through visible light irradiation. The method has good substrate universalityand relatively mild reaction conditions, is not only a substitute for synthesizing sulfone compounds by coupling from simple substrates reported at present, but also broadens the new application of the polyacid salt in the field of photocatalysis.

- Mo(VI) complex catalysed synthesis of sulfonees and their modification for anti-HIV activities
-
An efficient method for the synthesis of sulfones has been developed using sugar derived cis-dioxo molybdenum(VI) complex as catalyst and urea hydrogen peroxide as oxygen source. Present method is highly specific for sulfide oxidation irrespective of presence of alkene and aldehyde groups in the same molecule. Synthesis of fifteen sulfones have been reported with 82–98% isolated yields and the catalyst has been reused five times without any loss in its activity. 2-(Phenylsulfonyl)aniline has been condensed with eight different aromatic aldehydes and the products are being explored for HIV-1 reverse transcriptase inhibition activities.

- 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.

- 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.
