3-Aroylaziridines and 3-acylaziridines react with diphenylcyclopropenone with the formation of novel 4-aroyl-4-oxazolines and 4-acyl-4-oxazolines respectively. The unusual physical and chemical properties of these reactive heterocycles are discussed.

undergo thermal 1,3-dipolar addition to aromatic aldehydes and chloral via azomethine ylides to give exclusively 4-arenoyloxazolidines. Proof of the orientation of the addition was obtained and the formation of an alternative ring-expansion product was excluded by specific deuterium-labelling experiments. The lack of dependence of the course of the reaction on the stereochemistry of the aziridine, and
