Allylbenzene → 2-(Phenylmethyl)oxirane

참여 물질

반응 단계

A solution of m-chloroperbenzoic acid (mCPBA; 17 g, 0.1 mol) in 120 mL of methylene chloride was added (at ambient temperature) dropwise to a solution of allyl benzene (10 g, 85 mmol) in 200 mL of methylene chloride. After the reaction mixture was stirred for 5 h with a mechanical stirrer, 5 additional grams of m-CPBA were added and the reaction mixture stirred for another 2 h. The reaction mixture was then diluted with 200 mL of ether, washed with 2×100 mL of aqueous sodium bisulfite solution, 1×100 mL of aqueous sodium bicarbonate solution and 1×100 mL of brine. The organic solution was dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by bulb-to-bulb distillation (60° C., 0.1 mm) to give 8.5 g (77% yield) of 1-benzyl ethylene oxide as a clear colorless liquid.
