The use of an in situ generated Pd(0) catalyst associated to N,N′-bis(2,6-diisopropylphenyl)dihydroimidazol-2-ylidene (SIPr) as a ligand and t-BuONa as the base for sequential intra- followed by intermolecular aryl amination is described. The method has been applied to the synthesis of N-arylated five-, six- and seven-membered nitrogen heterocycles.
描述了一种使用原位生成的Pd(0)催化剂,该催化剂与N,N′-双(2,6-二异丙基苯基)二氢咪唑-2-亚基(SIPr)作为配体,以及t-BuONa作为碱,进行顺序的分子内和分子间芳基氨化的方法。这种方法已应用于合成N-芳基化的五、六和七元氮杂环。
