Application
Difluorocarbene Precursor
Experimental procedure: to a solution of 1,1-diphenylethylene (181.3 mg, 1.0 mmol) in diglyme (5 mL) is added a diglyme solution (10 mL) of sodium bromodifluoroacetate (78 mg, 0.40 mmol) dropwise for 10 min at 150 °C. Then, the reaction mixture is stirred for 5 min at 150 °C. After cooling to r.t., the reaction is quenched with ice water (30 mL). The organic materials are extracted with hexane (4 × 50 mL) and the combined organic layers are washed with brine (200 mL) and dried (Na2SO4). After removal of the solvent under reduced pressure, the residue is purified by silica gel column chromatography (hexane:EtOAc=100:1) to give 1,1-difluoro-2,2-diphenylcyclopropane (231.6 mg, 99%) as a colorless solid.
