iodination. The selection of appropriate environmentally friendly and cost-effective oxidants in combination with iodine for the iodination of aromatic rings, along with its application in the synthesis of natural products, holds significant importance. A highly efficient method utilizing I(III) as the initiator has been successfully developed for monoiodination of arylaldehydes. The method demonstrates good
碘是芳香族化合物碘化最有效的来源之一;然而,其亲电性不足以直接碘化。选择合适的环保且经济有效的氧化剂与碘结合用于芳环的碘化,及其在天然产物合成中的应用具有重要意义。已成功开发出一种利用 I( III ) 作为引发剂进行芳醛单碘化的高效方法。该方法与多种(杂)芳香醛具有良好的相容性,从而产生中等至优异的产率,且无需任何有毒、挥发性或爆炸性试剂。通过碘化和乌尔曼型偶联,合成了七种天然产物,即 aristogins A–F 和 Hernandial。
