The electron impact mass spectra of new 5-acetyl-4-aryl-6-methyl-2(1H)pyridones have been studied. A dominant peak in all the spectra is due to cleavage of the CO-NH bond of the amido group with charge retention on the carbonyl group. This fragmentation is followed by a hydrogen rearrangement to the
