| Abstract: | 5 new pyridazinone compounds,together with 3 known pyridazinone compounds were synthesized throng coupling and rearrangement reactions from substituted phenyl diazonium salts and 4-hydroxy-6-methyl-2-pyrone which were prepared from malonamic acid and acetone via 4 steps.The structures of 8 compounds were determined by elemental analysis,IR,and~1H-NMR. |
