Catalytic amination: The title reaction demonstrates the use of aryl carboxylates as suitable electrophilic coupling substrates in catalytic amination reactions. N‐heterocyclic carbene ligands and NaOtBu promote the amination of aryl pivalates through the cleavage of normally unreactive aryl carbon–oxygen bonds (see scheme; cod=cyclooctadiene).
催化胺化:标题反应表明在催化胺化反应中使用芳基羧酸盐作为合适的亲电子偶联底物。N-杂环卡宾配体和NaO t Bu通过裂解通常不活泼的芳基碳氧键来促进新戊酸芳基的胺化(参见方案; cod =环辛二烯)。

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
