The auto-oxidation of isobutyraldehyde in the presence of molecular oxygen generates acyloxy radicals, which in situ afford a hypervalent iodine compound with p-anisolyl iodide. A hypervalent iodine mediated reaction of N'-arylidene acetohydrazides provides substituted 1,3,4-oxadiazoles in good yields in parallel.
