title: Microwave-assisted palladium-catalyzed phosphonium coupling of 2(1H)-pyrazinones.
abstract: An expedient route for the synthesis of differently substituted 2(1H)-pyrazinones applying a microwave-assisted palladium-catalyzed phosphonium coupling procedure is reported. The method has also been successfully extended to some other tautomerizable heterocycles for efficient C-C cross-coupling.
