The invention relates to a method for preparing thiosulfonic acid ester compounds by direct oxidation of thiophenol. The method adds a thiophenol compound and a reaction accelerator into a solvent, uses oxygen (air) as an oxidant, and conducts the process at room temperature. Oxidation reaction; after the reaction, the crude product is obtained by extraction, drying and distillation, and the pure product is finally obtained by purification. The invention uses oxygen or oxygen in the air as the oxidant and NCS as the reaction accelerator, and has the advantages of short reaction steps, low temperature, simple operation and high yield, and is suitable for large-scale industrial production. |
