ResumoAbstract A series of 14 new 2; 4‐substituted‐δ 2 ‐1, 3, 4‐oxadiazolin‐5‐ones was prepared by a novel ring closure of the corresponding l‐acyl‐2, 2‐dialkylhydrazines with phosgene, whereby one alkyl group is lost as alkyl chloride. This new cyclization was carried out too with thiophosgene and with p ‐chlorothiobenzoic acid, 2, 2‐dimethylhydrazide to give the corresponding 2,4‐disubstituted‐δ 2 ‐1, 3, 4‐oxadiazoline‐5‐thione, ‐thiadiazolin‐5‐one and ‐thiadiazoline‐5‐thione, respectively.
