N-Methyl-N-tosyl trifluoromethanesulfenamide is a universal reagent for trifluoromethylthiolation of a broad scope of substrates^1,2. It is yellow solid, bench-stable, and soluble in alkanes, alcohols, diethyl ether, dichloromethane, DMF, and DMSO². The reagent reacts with heteroatomic nucleophiles, and organometallic reagents and can undergo aromatic electrophilic substitution with electron-rich aromatic and heteroaromatic compounds¹. Furthermore, terminal alkynes reacting with it in copper-catalyzed, base-free conditions to yield trifluoromethylthiolated alkynes or, if an electron-withdrawing substituent is present to yield vic-bistrifluoromethylthiolated vinylic products with (Z)-selectivity¹. The chemoselectivity of the reagent is controlled by the conditions of the reaction, which allows the usage of the reagent in the presence of many functional groups^{1, 2}.
