Iridium(I) complexes 1, containing bidentate phosphines, and 3, with arsine ligands, are generated in situ. These species mediate hydrogenisotopeexchange in a variety of aromatic substrates including benzyl ketones. Although the catalytic activities of complexes 1 and 3 are generally unexceptional, a logical step leads to the use of [ethylene-1,2-bis(diphenylarsine)](cyclooctadiene)iridium(I) tetrafluoroborate
