The nickel-catalyzed reaction of N-aryl amides with hydroborane or diboron reagents resulted in the formation of the corresponding reduction or borylation products, respectively. Mechanistic studies revealed that these reactions proceeded via the activation of the C(aryl)-N bonds of simple, electronically neutral substrates and did not require the presence of an ortho directing group.
N-芳基酰胺与氢硼烷或二硼试剂的镍催化反应分别导致形成相应的还原或硼化产物。机理研究表明,这些反应是通过激活简单的电子中性底物的 C(芳基)-N 键进行的,不需要邻位导向基团的存在。
