الإجراء التجريبي

In 400 ml of acetonitrile was dissolved 53.2 g of tetrahydrothiophene, and to the solution was gradually added a solution containing 100 g of phenacyl bromide dissolved in 300 ml of acetonitrile. The solution was stirred at room temperature for 3 hours to deposit powder. The reaction solution was poured into 1,500 ml of ethyl acetate, and the powder deposited was collected by filtration and dried to obtain 137 g of phenacylthiophenium bromide.
