| Abstract: | Arylmethylenemalononitriles 1 were treated with halo compounds under phase transfer catalysis (PTC) conditions to yield α-polyfunctional arylmethylene-malononitrile derivatives 2–4. The treatment of compounds 2–4 with hydrazine hydrate gave pyridinones 5,6 and pyridine 7, respectively. Triazines, triazepines, tetrazines, and triazoles 8–15 fused with pyridinone were synthesized by treating pyridinones 5 with a suitable reagent. |
