aurones was studied using cyclohexylamine and the most representative member of each class of these αβ-disubstituted ketones and α-halogeno chalcones. Overall yields of heterocyclic products were generally poor except from 4'6'-dimethoxy- and 3-nitro- substituted chalcone systems; aurones were obtained in fair yield from the former and in excellent yield from the latter. 22'-Diacetoxychalcone dibromide and
