Document Type and Number:
WIPO Patent Application WO/2022/179448
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of organic compound synthesis, and relates to a method for synthesizing (trifluoromethylthio) silver(I). The method for synthesizing (trifluoromethylthio) silver(I) (CAS No.: 811-68-7) comprises using silver fluoride as a raw material and trifluoromethyl thioate as a source of trifluoromethylthio to synthesize (trifluoromethylthio) silver(I). In the present invention, trifluoromethyl thioate is used as a source of trifluoromethylthio, and reacted with silver fluoride in a solvent to produce (trifluoromethylthio) silver(I), and a finished (trifluoromethylthio) silver(I) is obtained by means of separation and purification. The method for synthesizing (trifluoromethylthio) silver(I) of the present invention has the advantages of easily available raw materials, easily prepared reaction reagents and low price, significantly reduces the synthesis costs of (trifluoromethylthio) silver(I), has mild synthesis conditions and easy and safe operation, facilitates industrial production, has a high utilization rate of silver atoms, and is green and environmentally friendly.
