A facile synthetic method has been developed for the preparation of 6,8-(dibromo or diiodo)- -5-hydroxy-2-(phenyl or styryl)chromones. These compounds were obtained by either one-pot synthesis from 2'-benzyloxy-6'-hydroxychalcones or 2'-benzyloxy-6'-hydroxycinnamilydeneacetophenones or from the corresponding 2-phenyl- or 2-styrylchromones.
