A Hydrazone Ligand for Iridium-Catalyzed C-H Borylation: Enhanced Reactivity and Selectivity for Fluorinated Arenes
{{output}}
Ir-catalyzed C-H borylations of fluorinated and cyanated arenes with high meta-to-F/CN are described. Use of a dipyridyl hydrazone framework as the ancillary ligand and pinacolborane (HBpin) as the functionalizing reagent generates catalysts that are significa... ...
