Paragraph 0704-0710; 0712; 0714-0715; 0717-0720; 0722-0725, (2021/04/29)
The present invention relates to a method for manufacturing a sulfone and sulfonyl derivative compound using sodium (tert-butyldimethylsilyl)oxymethanesulfinate, which is a novel organic sulfin salt, wherein the novel organic sulfin salt has good stability, environmental friendliness and economy, and is easy to handle, and thus significantly reduces the amount of transition metal catalysts and the amount of organic sulfin salts used when introducing aryl or alkenyl. Also, alkylation, arylation, amination, and fluorination are all possible during secondary functionalization. Therefore, the present invention can be usefully used in preparation and mass production of various kinds of sulfones and derivatives thereof including asymmetric sulfone derivatives.

Paragraph 0144-0148, (2021/03/31)
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.
