参与物

反应步骤

Tetrahydrothiophene (53.2 g) was dissolved in 400 ml of acetonitrile, and thereto was slowly added a solution obtained by dissolving 100 g of phenacyl bromide in 300 ml of acetonitrile, and the solution was stirred at room temperature for 3 hours, thereby a powder was precipitated. The reaction solution was poured into 1,500 ml of ethyl acetate, and the powder was filtered out and dried, thus 137 g of phenacyltetrahydrothiophenium bromide was obtained.
