The Mitsonubo reagent (triphenylphosphine and dialkyl azodicarboxylates) was employed as a potential anionic nucleophile in a reaction involving aryl halides to produce aryl hydrazides. Aryl iodides and bromides, with electron-withdrawing as well as electron-releasing groups on the aromatic ring, undergo coupling reactions in good yields. The optimized conditions are developed for aryl iodides at room
Mitsonubo 试剂(三苯基膦和偶氮二羧酸二烷基酯)在涉及芳基卤化物以产生芳基酰肼的反应中用作潜在的阴离子亲核试剂。芳基碘化物和溴化物在芳环上具有吸电子和放电子基团,以良好的产率进行偶联反应。开发了室温下芳基碘和 60-75 °C 芳基溴的优化条件。
