  Copper-Mediated Direct Aryl C–H Cyanation with Azobisisobutyronitrile via a Free-Radical Pathway

  摘要：

  An unprecedented protocol for the copper-mediated direct cyanation of aryl C-H by employing 2,2'-azobisisobutyronitrwile (AIBN) as a free radical "CN" source is presented. The protocol not only provides a more efficient pathway for the synthesis of aryl nitriles in terms of the yields and the loading amount of copper salts but also, more importantly, represents a novel strategy for aryl C-H cyanation via a CN free-radical mechanism as compared to the CN anion-participating protocols often reported.

  The copper-catalyzed cyanation of arenes using benzyl nitrile as a cyanide anion surrogate furnishes aromatic nitriles in moderate to good yields. The cascade process involves a copper-catalyzed aerobic C-H oxidation, a retro-cyanohydrination, and a copper-catalyzed aerobic oxidative C-H functionalization.

  Cut and paste! A Cu‐catalyzed aromatic CH cyanation with acetonitrile as the nitrile source by CCN 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 CCN cleavage and enhancing the reaction rate.
