Abstract

A method for the efficient and reliable synthesis of aryl nitriles via the Cu2O-catalyed cross-coupling of aryl boronic acids or esters and TMSCN is presented. A broad range of substrates decorated by electron-rich and deficient, sterically very congested, and labile functionalities were tolerated. Moreover, the reaction can proceed under mild conditions at room temperature. These advantages paired with the use of cheap, readily available, and halogen-free Cu2O as catalysts make the protocol an appealing option for aryl cyanations.
