Aliphatic compounds substituted with medicinally important trifluoromethylthio (SCF3) and trifluoromethylselenyl (SeCF3) groups were synthesized directly from alcohols by using the new benzothiazolium salts BT‐SCF3 and BT‐SeCF3. These bench‐stable fluorine‐containing reagents are facile to use and can be prepared in two steps from non‐fluorinatedheteroaromatic starting materials. The metal‐free d

Direct Dehydroxytrifluoromethylthiolation of Alcohols Using Silver(I) Trifluoromethanethiolate and Tetra-<i>n</i>-butylammonium Iodide
reaction for the direct trifluoromethylthiolation and fluorination of alkyl alcoholsusing AgSCF3 and nBu4NI has been developed. The trifluoromethylthiolated compounds and alkyl fluorides were selectively formed by changing the ratio of AgSCF3/nBu4NI. This protocol is tolerant of different functional groups and might be applicable to late‐stage trifluoromethylthiolation of alcohols.
