Repurposing a supramolecular iridium catalyst via secondary Zn⋯OC weak interactions between the ligand and substrate leads to ortho -selective C(sp 2 )–H borylation of benzamides with unusual kinetics

Supramolecular catalysts based on a zinc-porphyrin molecular recognition site and a catalytically active iridium site enabled the selective
ortho
-C–H borylation of benzamides under a regime in which the C–H activation step is not rate-determining.
