Abstract
The reaction of aziridines with phenyl and p-chlorophenylpropiolyl chlorides at —30 to 60°C leads only to 1,2-addition products, viz., α-acetylenic ethyleneimides, or their isoraerization products, viz., 2-ethynyl-substituted 2-oxazolines. Reactions with amines showed that the p-chlorophenylpropiolic acid ethyleneimides obtained are mild N-acylating agents.
