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 transformation controlled by a Lewis acid–base interaction between a ligand and a substrate. The C−H borylation reaction could be conducted on a gram scale, and with a bioactive molecule as a substrate, demonstrating its applicability to late‐stage regioselective C−H borylation. A bioactive molecule was synthesized from an ortho‐borylated product by converting the boryl and methylthio groups of the product.
Eine Ir/Bipyridin‐katalysierte ortho‐selektive C‐H‐Borylierung von Arylsulfiden wurde entwickelt. Die hohe ortho‐Selektivität resultiert aus der Lewis‐Säure‐Base‐Wechselwirkung zwischen einer Borylgruppe des Liganden und einem Schwefelzentrum des Substrats. Dies ist das erste Beispiel einer katalytischen und regioselektiven C‐H‐Transformation, die durch eine Lewis‐Säure‐Base‐Wechselwirkung zwischen Ligand und Substrat gesteuert wird.
