Cut and paste! A Cu‐catalyzed aromatic CH cyanation with acetonitrile as the nitrile source by CCN cleavage has been developed (see scheme; TMEDA=N,N,N′,N′‐tetramethylethylenediamine). The reaction is catalytic in copper, and it is found that using (Me3Si)2 as an additive plays a critical role in promoting CCN cleavage and enhancing the reaction rate.
剪切和粘贴!已开发出一种通过CCN裂解的乙腈为腈源的Cu催化的芳族CH氰化反应(参见方案; TMEDA = N,N,N ′,N′-四甲基乙二胺)。该反应在铜中是催化的,发现使用(Me 3 Si)2作为添加剂在促进CCN裂解和提高反应速率方面起着关键作用。
