Application
TCI Practical Example: Trifluoromethylation Catalyzed by Photoredox Catalyst
-
Used Chemicals
-
- 4-Methylstyrene (stabilized with TBC) [M0428]
- Tris(2,2'-bipyridine)ruthenium(II) Bis(hexafluorophosphate) (= Ru(bpy)3(PF6)2) [T3435]
- 5-(Trifluoromethyl)dibenzothiophenium tetrafluoroborate
- Acetonitrile
- Ion-Exchanged Water
-
Procedure
To a solution of 5-(trifluoromethyl)dibenzothiophenium tetrafluoroborate (0.171 g, 0.50 mmol, 1.0 eq), Ru(bpy)3(PF6)2 (0.0022 g, 0.0025 mmol, 0.5 mol%) in acetonitrile (10 mL) and ion-exchanged water (1 mL) was added 4-methylstyrene (0.079 mL, 0.60 mmol, 1.2 eq) at rt under N2. The mixture was placed at a distance of 2-3 cm from Blue LED lamp. The orange solution was stirred at rt under visible light irradiation. After 5 hours, water (10 mL) and dichloromethane (15 mL) was added. The reaction mixture was separated. The water phase was extracted with dichloromethane (5 mL, 2 times). The organic phase was corrected, washed with brine (50 mL), dried over sodium sulfate and filtered. The solvent was removed under reduced pressure and the residue was purified by column chromatography on silica gel (hexane:ethyl acetate = 11:1 - 71:29 - 1:4), giving N-(1-(4-methylphenyl)-3,3,3-trifluoropropyl)acetamide as a white solid (80 mg，y. 65%).

Experimenter’s Comments
-
Acetonitrile was degassed by nitrogen for 1 hour before use.
Irradiation of visible light was performed with Kessil A160WE Tuna Blue 40W×2.
The reaction mixture was monitored by 1H NMR.
