반응 조건

반응 단계

To a 100 ml round bottom flask was added 3,5-difluorophenol (3.85 g, 29.6 mmol), vinylacetate (5.1 g, 59.2 mmol), Na2CO3 (1.88 g, 17.8 mmol), chloro-1,5-cycooctadiene iridium (I) dimmer (199 mg, 0.296 mmol) and 10 ml toluene. The resulting reaction mixture was flushed with nitrogen and heated at 100° C. overnight. After cooling to room temperature, the reaction mixture was diluted with 60 ml hexane and washed with 60 ml water. The organics were dried over sodium sulfate, filtered through a pad of silica gel, rinsed with 60 ml hexane. The filtrates were concentrated to give 3.25 g desired product as colorless liquid.
