Clever positioning: A bipyridine ligand incorporating a remote anionic sulfonate group directs iridium-catalyzed borylation to the meta-position on a range of amide-containing arenes. It is proposed that this selectivity is a result of a hydrogen bonding interaction to correctly position the iridium metal centre in the crucial C−H activation.
