  We report a method to conduct one-pot meta cyanation of arenes by iridium-catalyzed C-H borylation and copper-mediated cyanation of the resulting arylboronate esters. This process relies on a method to conduct the cyanation of arylboronic esters, and conditions for this new transformation are reported. Conditions for the copper-mediated cyanation of arylboronic acids are also reported. By the resulting

The process occurs through Ir‐catalyzed CH borylation, followed by Pd‐ or Ni‐catalyzed coupling with alkyl electrophiles. This selectivity complements that of the typical Friedel–Crafts alkylation; meta‐selective alkylation of a broad range of arenes with various electronic properties and functional

In this paper, NNB-type boryl anions were designed as tridentate ligands to promote aryl C–H borylation. In combination with [IrCl(COD)]2, they generate a highly active catalyst for a broad range of (hetero)arene substrates, including highly electron-rich and/or sterically hindered ones. This
