Wang, Fei published the artcileTransition-metal- and phosphorus-free electrophilic trifluoromethylthiolation of indoles with sodium trifluoromethanesulfinate in ionic liquids, Recommanded Product: 1-Iodohexane, the publication is Tetrahedron Letters (2021), 153015, database is CAplus.
An acid-promoted protocol has been developed to achieve the transition-metal- and phosphorus-free electrophilic trifluoromethylthiolation of indoles I (R = H, 4-Me, 5-benzyloxy, 6-F, etc.; R1 = H, Me, Et; R2 = H, Ph) using sodium trifluoromethanesulfinate in an imidazolium-based ionic liquid ([Hmim]Br) to obtain subtd. ((trifluoromethyl)thio)-1H-indole derivatives II. The [Hmim]Br not only acts as a recyclable solvent, but also as the reductant in this transformation. The advantages of this chem. include simple operation, use of a recyclable solvent, avoidance of transition-metal and phosphorus, and gram-scale synthesis.
