The trifluoromethyl and thioether groups are widely employed in the design of drug molecules. A hydrothiolation reaction of α-(trifluoromethyl)styrenes with thiophenols under solvent-free conditions is reported, which is promoted by tetrabutylammonium fluoride [TBAF, 1 mol/L in tetrahydrofuran (THF)]. This strategy features simple operation, mild reaction conditions, excellent functional group tolerance, and high chemoselectivity. The method demonstrates high atom economy, affording the target products in up to 95% yield, thus providing a concise and efficient alternative approach for the synthesis of β-trifluoromethyl thioethers.

Key words: tetrabutylammonium fluoride (TBAF), hydrothiolation reaction, α-(trifluoromethyl) styrene, β-trifluoromethyl thioethers
