Herein we develop a metal-free umpolung dehydroxytrifluoromethylthiolation of alcohols with commercially available PPh3 and N-trifluoromethylthiophthalimide within 30 minutes. This protocol shows excellent functional group tolerance and high regioselectivity. The dehydroxytrifluoromethylthiolation of a series of natural products and drugs further demonstrates its practicality. Preliminary mechanistic studies suggest that PPh3 is responsible for deoxygenation and the key trifluoromethylthiophosphonium ion may be hydrolyzed by H2O in solvent.

Organic & Biomolecular Chemistry
Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
