Abstract

Benzamide oxime reacts with oxalyl chloride (molar rate 2∶1) to give the oxadiazino-oxadiazine derivative3. Benzamide oxime O-ethers and oxalyl chloride cyclize in boiling xylene yielding 3-phenyl-4.5-dihydro-1.2.4-oxadiazol-5-one (7) or5, depending on the reaction time. The imidazolium salt4 is postulated as the common intermediate.

Zusammenfassung

Benzamidoxim reagiert mit Oxalylchlorid zum Oxadiazino-oxadiazin-Derivat3. Benzamidoxim-äther und Oxalylchlorid cyclisieren sich je nach Reaktionsdauer in siedendem Xylol über das entsprechende Imidazolium-Salz4 entweder zum 3-Phenyl-4,5-dihydro-1,2,4-oxadiazol-5-on (7) oder, wie im Falle des Äthyl-äthers, zur Verbindung5 (C11H12N2O2).
