应用
TCI Practical Example: Trifluoromethylthiolation Reaction Using Silver(I) Trifluoromethanethiolate
-
Used Chemicals
-
Procedure
-
Silver(I) trifluoromethanethiolate (907 mg, 4.34 mmol), tetrabutylammonium iodide (4.81 g, 13.0 mmol) and 4-methoxybenzyl alcohol (200 mg, 1.45 mmol) were dissolved in toluene (15 mL) and stirred at 80 °C for 19 hours. The reaction mixture was cooled to room temperature and filtered through a plug of silica gel (eluted with ethyl acetate). The solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (hexane) to give (4-methoxybenzyl)(trifluoromethyl)sulfane as a colourless oil (216 mg, 67% yield).

应用
Trifluoromethylthiolating Agent Usable for Direct Dehydroxytrifluoromethylthiolation of Alcohols
Experimental procedure3): AgSCF3 (251 mg, 1.2 mmol, 3.0 eq.) and TBAI (1330 mg, 3.6 mmol, 9.0 eq.) are combined in a Schlenk tube. The tube is mounted with a reflux condenser and backfilled with N2, then toluene (4.0 mL) and alcohol (0.4 mmol, 1.0 eq.) are added. The tube is placed into a preheated oil bath at 80 °C with vigorous stirring. After 10 h, the reaction mixture is cooled to room temperature and filtered through a plug of silica (eluted with EtOAc). The filtrate is concentrated, and the product is purified by column chromatography on silica gel to give the desired product.
