Reaction Steps
To 2-vinyloxazoline-4,5-dione hydrochloride (100 g; 0.62 mol), o-dichlorobenzene (400 g) was added, and the resultant mixture was heated at 110° to 120° C. while stirring for about 30 minutes. After cooling with ice, the reaction mixture was distilled under reduced pressure to give acryloyl isocyanate (8.9 g) and beta-chloropropionyl isocyanate (56.4 g).
