Herein, we report the direct synthesis of a wide variety of functionalized aromatic bromides, chlorides, iodides, and fluorides from nitroarenes in a sequential one-pot operation. This protocol is based on an air- and moisture-tolerant dioxomolybdenum-catalyzed reduction of nitroaromatics, employing pinacol as a reducing agent, which enables subsequent diazotization and halogenation steps. This methodology
在此,我们报道了在连续的一锅操作中从硝基芳烃直接合成各种官能化芳香族溴化物、氯化物、碘化物和氟化物。该方案基于耐空气和耐湿气的二氧钼催化硝基芳香族化合物的还原,采用频哪醇作为还原剂,从而实现后续的重氮化和卤化步骤。该方法代表了直接从硝基芳族化合物合成卤代芳族化合物的经济、实用和替代程序。
