We have developed the divergent deaminative borylation and hydrodeamination of primary aromatic amines using bis(pinacolato)diboron. These transformations can be switched by the reaction conditions. Mechanistic and computational studies have suggested that the cleavage of the C–N bond and the formation of C–B bond are unlikely to involve free aryl radical intermediates. However, hydrodeamination is
我们开发了使用双(频哪醇)二硼对芳香伯胺进行不同的脱氨基硼化和加氢脱氨基。这些转变可以通过反应条件来切换。机械和计算研究表明,C-N 键的断裂和 C-B 键的形成不太可能涉及游离芳基中间体。然而,加氢脱氨作用是通过相应的芳基和醚溶剂之间的氢原子转移进行的。
