Mild room-temperature palladium-catalyzed C3-arylation of 2(1H)-pyrazinones via a desulfitative Kumada-type cross-coupling reaction.
An efficient desulfitative Kumada-type cross-coupling protocol is reported for the C3-arylation of 5-chloro-3-(phenylsulfanyl)pyrazin-2(1H)-ones. The method has also been successfully extended to the arylation of some (hetero)aryl thioethers and thioesters.
