Aryl nitriles can be efficiently synthesized through transition-metal-mediated cyanation of aryl halides, arenes, aryl boronic acids, and so on. Among those most commonly used transition-metals, copper catalysts are surely much more inexpensive and easier to handle, compared to any other metal catalysts. Considering the high-efficiency of copper catalysts in the activation of C–X, C–H, and C–B bond...
An efficient copper-mediated synthesis of aryl nitriles from aryl boronic acids has been achieved using benzyl cyanide as a user-friendly cyanide source. Various aryl boronic acids underwent the reaction smoothly, affording the corresponding aryl nitriles in moderate to good yields. tert-Butyl hydroperoxide (TBHP) was found to be a critical agent facilitating the cyanation reaction.
