Participants

Reaction Steps

3-Chloropropanol (47.3 g, 0.50 mole) and a catalytic amount of triethylamine at 65° were treated dropwise with 42 g (0.50 mole) of diketene. After the addition was complete, the reaction was stirred at 65° for an additional hour. Distillation of the residue furnished 72.9 g (82%) of product as a clear liquid, b.p. 78°-85° at 150 mm.
