Abstract: 4-Allyloxypyridine-l-oxide(IV)has been synthesized in good yield by tre ating 4-chloropyridine-l-oxide with sodium aliyloxide in allyl alcohol under mild condition. On heating under vacuum, (IV) is found to be transformed into N-allyl-4-pyridone (V) and 3-allyl-4-hydroxypyridine-1-oxide (VI) by Ciaisen rearrangement.
