The coupling of arylboronic acids with electron-deficient nitroarenes was realized for the first time by using a rhodium(I) catalyst under an air atmosphere, achieving unsymmetrical diaryl ethers with yields ranging from poor to good. From a deuterium labeling experiment, the oxygen atom is derived from ambient water. The efficiency of this reaction was demonstrated by its compatibility with fluoro, bromo, chloro, and trifluoromethyl groups.
首次在空气氛围中使用铑（I）催化剂实现了芳基硼酸与缺电子硝基芳烃的偶联，得到了产率从差到好的不对称二芳基醚。通过氘标记实验，氧原子来自环境水。该反应的效率通过其与氟、溴、氯和三氟甲基的兼容性得到证明。
