title: N-heterocyclic carbene catalyzed aroylation of 3,5-dichloro-2(1H)-pyrazinones.
abstract: The N-heterocyclic carbene catalyzed chemoselective C3-aroylation of 3,5-dichloro-2(1H)-pyrazinones with various aldehydes is reported. We herein describe results of this remarkable mild and efficient procedure.
