A FACILE PREPARATION OF 3-HALOFLAVONES USING HYPERVALENT IODINE^* CHEMISTRY

Abstract

Various 3-haloflavones were prepared by the reaction of the corresponding flavone derivatives with iodobenzene diacetate and trimethylsilyl halide under mild reaction conditions. The iodobenzene diacetate could be replaced by the polymer supported iodobenzene diacetate without the decreasing activity.
