One-pot method of preparing aryl sulfonic fluoroform thioester series compounds through one-pot method

The invention discloses a one-pot method of preparing aryl sulfonic fluoroform thioester series compounds, and belongs to the technical field of organic chemistry.The method includes the two steps that 1, arylamine is adopted as a reaction substrate, tert-butyl nitrite is used as an oxidizing agent, and arylamine is oxidized into aryl diazonium salt in situ; 2, the aryl diazonium salt generated in situ is captured by SO2 and SCF3+, and the aryl sulfonic fluoroform thioester series compounds are obtained without separating and purifying a reaction intermediate.By means of the method and a cascade reaction strategy, aryl sulfonic fluoroform thioester can be synthesized from arylamine through the one-pot method.The one-pot cascade reaction is mild in condition, wide in substrate applicability, easy to operate, low in cost, high in product purity and suitable for large-scale preparation, few side products are generated, and separation and purification are convenient.
