An unprecedented reaction for the direct trifluoromethylthiolation and fluorination of alkyl alcohols using AgSCF3 and nBu(4)NI has been developed. The trifluoromethylthiolated compounds and alkyl fluorides were selectively formed by changing the ratio of AgSCF3/nBu(4)NI. This protocol is tolerant of different functional groups and might be applicable to late-stage trifluoromethylthiolation of alcohols.
