An efficient, palladium acetate-catalysed, tributylphosphine-promoted direct synthesis of symmetrical diaryl ethers through the self-coupling of aryl fluorides has been developed with K2CO3/ZrO2 as a base. This provides an alternative method to prepare aromatic polymers, important synthetic intermediates and natural products for use in the field of pharmaceuticals and industrial materials.
以 K2CO3/ZrO2 为碱,通过芳基氟化物的自偶联,开发了一种高效的、乙酸钯催化的、三丁基膦促进的对称二芳基醚的直接合成。这为制备用于制药和工业材料领域的芳香族聚合物、重要的合成中间体和天然产物提供了一种替代方法。
