Rhodium(I) complexes of the form [(PNP)Rh(OR)] (R=H, CH2CF3, C6H5; PNP=2,6-bis[(di-tert-butylphosphino)methyl]pyridine) have been prepared. Upon thermolysis in [D6]benzene, the hydroxide and trifluoroethoxide complexes undergo benzene activation. [(PNP)Rh(OC6H5)] is an active catalyst for the H/D exchange between D2O and benzene and between H2O and [D8]toluene (see scheme), for which exchange occurs selectively at the meta and para positions.
