para‐Selective C−H borylation of benzamides and pyridines has been achieved by cooperative iridium/aluminum catalysis. A combination of iridium catalysts commonly employed for arene C−H borylation and bulky aluminum‐based Lewis acid catalysts provides an unprecedented strategy for controlling the regioselectivity of C−H borylation to give variously substituted (hetero)arylboronates, which are versatile synthetic intermediates for complex multi‐substituted aromatic compounds.
Collect. Select. Reflect: para‐Selective C−H borylation of benzamide and pyridine adducts is controlled by a combination of iridium and bulky aluminum‐based Lewis acid catalysts. Variously substituted (hetero)arylboronates were prepared, which are versatile synthetic intermediates for complex multi‐substituted aromatic compounds.
