In order to find a good method to iodinate directly the C-5 of uracil derivatives, we investigated three methods, which included iodine/lead （IV） dioxide, iodine/ammonium hexanitratocerate （CAN） and iodine chloride, and examined their reactivity to different types of uracil and thiouracil derivatives.展开更多
