Thermally, or in the presence of p-toluenesulfonic acid, 3-acyl-5-acylamino-2,3-dihydro-1,3,4-thiadiazole 1-oxides are transformed into 1,3,4-oxadiazoles, carbonyl compounds and sulfur.
Stereoselective S-Oxidation of 5-Substituted 4-Acetyl-Δ2-1,3,4-thiadiazolines: X-Ray Crystal Structure of 4-Acetyl-2-acetylamino-5-methyl-5-phenyl-Δ2-1,3,4-thiadiazoline 1-Oxide

N.m.r. spectroscopy and X-ray crystallography show that oxidation of 5-substituted 4-acetyl-2-acetylamino-Δ2-1,3,4-thiadiazolines with m-chloroperbenzoic acid gives the corresponding Δ2-1,3,4-thiadiazoline 1-oxides; the novel reactions of the product (2a) are also described.
