A homogeneous rhodium-indium catalyst hydrodefluorinates substrates bearing strong aryl C-F bonds, including difluoro- and fluorobenzene, using 1 atm of H2, alkoxide bases, and moderate temperatures (70-90 °C). Characterization of catalytic intermediates establishes a formal Rh-I/RhI redox cycle. The Rh → In interaction is proposed to enable catalysis by stabilizing the reactive Rh-I species, which is responsible for cleaving the Ar-F bond and is ultimately regenerated using H2 and base.
