Preparation
Ammonia was passed into a solution of allyl chloroformate (368 g, 3 mol) in benzene (1000 mL) at 25–35 °C until the reaction was complete. The ammonium chloride produced was filtered off and the salt was washed with small quantities of benzene. Distillation of the benzene solution through a short column gave 255 g (85% yield) of allyl carbamate (allyl urethane), bp 73–75 °C at 2 mmHg.
