We report a straightforward and efficient reaction protocol for the syntheses of substituted ureas via treatment of thioureas with aqueous potassium dichloroiodate (KICl2). By tuning the reaction condition, thioureas bearing activated N-aryl substituents may undergo either selective oxidation or sequential oxidation and iodination, forming iodoaryl ureas in the latter case.
我们报告了一种直接和有效的反应方案,用于通过硫代脲与二氯碘酸钾水溶液(KICl 2)的处理来合成取代的脲。通过调节反应条件,带有活化的N-芳基取代基的硫脲可以进行选择性氧化或顺序氧化和碘化,在后一种情况下形成碘代芳基脲。
