Procedure
-
A solution of dtbpy (27 mg, 0.05 mmol), bis(pinacolato)diboron (1.0 g, 4.0 mmol) and [Ir(cod)OMe]2 (33 mg, 0.025 mmol) in cyclohexane (40 mL) was stirred under nitrogen at room temperature for 10 min. Benzo[1,2-b:4,5-b']dithiophene (1.0 g, 4.0 mmol) was added the mixture and stirred 80 ˚C for 18 hours. The reaction mixture was quenched with water and separated both layers, extracted with dichloromethane. The organic phase was dried over anhydrous sodium sulfate and filtered. The solvent was removed under reduced pressure and the crude was washed with methanol (20 mL) to give 1 as a white solid (0.771 g, 87% yield).

Experimenter’s Comments
-
The reaction mixture was monitored by NMR.
Cyclohexane was bubbled with nitrogen before use.

Application
ortho-Allylation of 1-Arylpyrazoles via Iron-Catalyzed C-H Bond Activation
Typical Procedure (X = H): 1-Phenylpyrazole (116 mg, 0.8 mmol) and ZnCl2-TMEDA (606 mg, 2.4 mmol) are placed in a dried Schlenk flask under argon. A solution of PhMgBr in THF (1.09 M, 4.40 mL, 4.8 mmol) is added dropwise to this mixture at 0 °C. After stirring for 3 min, allyl phenyl ether (220 µL, 1.6 mmol) and a solution of Fe(acac)3 / 4,4’-di-tert-butyl-2,2’-bipyridyl in THF (1.0 mL, 0.08 M, 80 µmol) are sequentially added. The reaction mixture is stirred at 0 °C for 48 h, and then it is diluted with Et2O, followed by the addition of a saturated aqueous solution of Rochelle salt tetrahydrate (L-(+)-tartaric acid potassium sodium salt tetrahydrate). After extraction with ethyl acetate, the combined organic layers are filtered through a pad of Florisil, and concentrated under reduced pressure. The crude product is purified by column chromatography on silica gel (eluent: hexane/AcOEt/NEt3 = 99/0.5/0.5), followed by gel-permeation chromatography (eluent: toluene) to afford 1-(2-allylphenyl)-1H-pyrazole as a colorless oil (118 mg, 80% yield).
