Abstract
Seven kinds of vinyl ketones and two kinds of γ-diketones were synthesized by reacting two kinds of methyl ketones and five kinds of aldehydes in acetic acid, with addition of a small amount of sulfuric acid, at 40° for 2-7 days or by refluxing in acetic anhydride for 2-3 hours. From the reaction of these synthesized vinyl ketones (three kinds) and γ-diketones (two kinds) with carbonyl reagents, six kinds of derivatives, including 3, 5-bis(5-nitro-2-furyl)pyridazine (XVIa), were synthesized.
