Reaction Steps
A solution of 2,3,3-trifluoro-2-propenyl bromide (5.25 g, 30 mmol) and triethyl phosphite (4.15 g, 25 mmol) in acetonitrile (15 mL) was heated at reflux for overnight. The residue obtained after evaporation of the solvent was chromatographed over silica gel (hexanes/ethyl acetate/ethanol, 80/20/1) to give diethyl (1,1,2-trifluro-2-propenyl)phosphonate (0.8 g, 11%) and diethyl (2,3,3-trifluro-2-propenyl)phosphonate (1.0 g, 14%).
