Butyl Acrylate → HCID 58473636, compound

Participants

Reaction Steps

After 2,7-dibromofluorene (8.02 g) and benzyltriethylammonium chloride (0.56 g) were dissolved in 30 mL of benzene, 8 mL of an aqueous 50% sodium hydroxide solution was added dropwise under a nitrogen atmosphere, followed by stirring for 15 minutes. N-butyl acrylate (12.65 g) was added dropwise and the mixture was reacted at room temperature for 5 hours. The reaction solution was diluted with 200 mL of ethyl acetate, washed three times with water, washed once with brine, and then the organic layer was dried over magnesium sulfate. The solution was filtered and the solvent was distilled off. The solution was purified by silica gel column chromatography using dichloromethane as an eluent and then recrystallized from hexane to obtain (2,7-dibromo)-9H-fluorene-9,9-dipropionic acid (F2COOBuBr2) (7.87 g, 55%).
