使用全氟高价碘(III)化合物作为极端单电子转移(SET)氧化剂,首次实现了芳香醚之间的分子间C-H交叉偶联。这种特定偶联的证明可以提供一种直接的途径,以有价值的氧化混合萘-苯联芳基化合物3,而不会形成其他联芳基衍生的副产物。
The intermolecular C-H cross-coupling between aromatic ethers has been achieved for the first time using perfluorinated hypervalent iodine(III) compounds as extreme single-electron-transfer (SET) oxidants. The demonstrations of this specific coupling could provide a direct route to valuable oxygenated mixed naphthalene-benzene biaryls 3 only, without formation of other biaryl-derived byproducts.
