Hydrochloric Acid → Styrene Oxide

Participants

Reaction Steps

To 1.818 g (17.456 mmol) of styrene dissolved in 5 ml of dichloromethane in 250 ml round bottom flask, 5 ml of 12 N hydrochloric acid and 10 ml of water were added. A mixture of (3.035 g, 29.47 mmol) NaBr and 0.879 g (5.819 mmol) of NaBrO3 dissolved in 20 ml water was added under stirring at room temperature over a period of 90 min. The organic layer was evaporated to get 39.3% of styrene dibromide, 60.6% styrene epoxide and 0.01% benzaldehyde.
