Dipyridylarylmethane derivatives represent a newly introduced class of ligands for iridium-catalyzed alkane C-H borylation which give some of the most active catalysts known. Using modular synthetic routes, we show that ligand substitution plays a major role in determining catalyst activity and speciation. New and more-accessible iridium precatalysts are explored with the aim of supplanting (mesitylene)Ir(Bpin)<sub>3</sub>.
