Iridium-catalyzed alkane C-H borylation has long suffered from poor atom economy, resulting both from inclusion of only a single boron equivalent from the diboron reagent and a requirement for neat substrate. Appropriately-substituted dipyridylarylmethane ligands are found to give highly active alkane borylation catalysts which facilitate C-H borylation with improved conversion efficiency. This system provides for
