The Intermolecular Hydroamination of the Unactivated Alkene and the Dialkylamine Catalyzed Using a Photoredox Catalyst

Used Chemicals


2,4,6-Triisopropylbenzenethiol (0.060 g, 0.25 mmol, 0.5 eq), piperidine (0.050 mL, 0.50 mmol, 1.0 eq), 4-methoxystyrene (0.10 mL, 0.75mmol, 1.5 eq), Ir[dF(Me)(ppy)2(dtbbpy)]PF6 (10 mg, 0.0099 mmol, 2.0 mol%) were dissolved in toluene (10 mL) at rt under N2. The mixture was placed at a distance of 2-3 cm from Blue LED lamp with a cooling fan. The yellow orange suspension was stirred at rt under visible light irradiation until the amine was completely consumed. After 12 h of irradiation, the reaction mixture was diluted with ethyl acetate (20 mL) and extracted with 1 mol/L HCl aq. (70 mL x 2). The combined aqueous layer was washed with diethyl ether (30 mL x 2), then neutralized with 2 mol/L NaOH aq. (78 mL) to pH 7 and then saturated sodium bicarbonate aq. (10 mL) was added to ensure slightly basic conditions. The aqueous layer was extracted with dichloromethane (50 mL x 3). The combined organic layer was dried over sodium sulfate (30 g) for about 30 minutes and then filtered. The solvent was removed in vacuo to give compound 1 as a colorless oil (39 mg, y. 35%).

Experimenter’s Comments

Toluene was degassed with nitrogen for 30 minutes before use.
Irradiation of visible light was performed with Kessil A160WE Tuna Blue 40Wx2.
The reaction mixture was maintained at rt by a cooling fan.
The reaction mixture was monitored by 1H NMR and GC.
