An iridium/bipyridine‐catalyzed ortho‐selective C−H borylation of aryl sulfides was developed. High ortho‐selectivity was achieved by a Lewis acid–base interaction between a boryl group of the ligand and a sulfur atom of the substrate. This is the first example of a catalytic and regioselective C−H...
