The first successful catalytic borylation of unactivated aromatic C–N bonds of tertiary anilines without the preactivation or any directing groups is demonstrated. The reactivity of both N,N-dialkylarylamines and N-arylpyrroles were investigated systematically, and the targeted products were furnished in moderate to good yields. The DFT calculation results indicated that the catalytic cycle is furnished
证明了未激活或没有任何导向基团的叔
苯胺未活化芳族C–N键的第一个成功的催化
硼化反应。系统地研究了N,N-二烷基芳基胺和N-芳基
吡咯的反应性,并以中等至良好的产率提供了目标产物。DFT计算结果表明,由于Ni / NHC催化体系的空间位阻,通过五元循环过渡态提供了催化循环。
