title: Palladium-catalyzed oxidative carbonylation of hydrazides: synthesis of 1,3,4-oxadiazol-2(3H)-ones.
abstract: A novel palladium-catalyzed oxidative carbonylation reaction was developed via the carbon monoxide insertions between the amine group and the carbonyl group to realize the intramolecular cyclization, which provides efficient access to 1,3,4-oxadiazol-2(3H)-ones with a wide range of substrates under mild conditions, resulting in good to excellent yields.
