  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.

• Cobalt-Catalyzed C–H Cyanation of (Hetero)arenes and 6-Arylpurines with <i>N</i>-Cyanosuccinimide as a New Cyanating Agent

  A cobalt-catalyzed C–H cyanation reaction of arenes has been developed using N-cyanosuccinimide as a new electrophilic cyanating agent. The reaction proceeds with high selectivity to afford monocyanated products with excellent functional group tolerance. Substrate scope was found to be broad enough to include a wide range of heterocycles including 6-arylpurines.

  A rhodium-catalyzed aromatic C–H bond direct cyanation with safe, bench-stable, and commercially available dimethylmalononitrile as the cyanating agent has been successfully developed by using copper oxide as a promotor. Pyridine, quinoline, pyrimidine and pyrazole were used as the directing group in this type of C–H bond direct cyanation reaction.

  A rhodium-catalyzed cyanation of chelation assisted C-H bonds is described employing N-cyano-N-phenyl-p-methylbenzenesulfonamide as an efficient cyanating reagent. The present method allowed the synthesis of various benzonitirle derivatives in good to excellent yield. A number of chelating groups are also effective in the present cyanation of C-H bonds. In addition, the developed methodology was applied in the formal synthesis of the isoquinoline alkaloid, menisporphine.
