syntheses of diarylamines from a palladium-catalyzed reductive Buchwald-Hartwig amination of nitroarenes with aryl (pseudo)halides is developed. The use of upstream nitroarenes as arylamine surrogates, the judicious selection of bis(pinaco-lato)diboron (B2pin2) as a stoichiometric reducing agent, wide substrate scope including (hetero)aryl halides (Cl, Br and I) and aryl triflates, constitute the striking
开发了一种由钯催化的硝基芳烃与芳基(拟)卤化物的还原 Buchwald-Hartwig 胺化反应从头催化合成二芳基胺的方法。使用上游硝基芳烃作为芳胺替代物,明智地选择双(频哪醇)二硼 (B 2 pin 2 ) 作为化学计量还原剂,广泛的底物范围包括(杂)芳基卤化物(Cl、Br 和 I)和芳基三氟甲磺酸盐构成了该议定书的显着特征。
