Oxidation of cycloheptatriene (IV) with selenium dioxide in hydrous dioxane afforded tropone (I) which was derived to its acylhydrazones. The benzoylhydrazone of (I) was isolated in two forms of keto (V) and enol (VI) types. Of the substituted benzoylhydrazone, p-methyl- (VIII) and p-methoxy-benzoylhydrazone (IX) were isolated in keto form, and p-nitro- (X), m-nitro- (XI), and 3, 5-dinitro-benzoylhydrazones (XII) were isolated in enol form crystals, isonicotinoylhydrazone (XIII) also came in enol type.
