چکیده
A set of bimetallic complexes based on iridium and rhodium with bis(diphenylphosphino)methane, bis(di-iso-propylphosphino)methane, diphenyl-2-pyridylphosphine 2-(di-iso-propylphosphino)imidazole bridging ligands was prepared. The were characterized by NMR IR spectroscopy studied quantum-chemically using DFT methods. systems succeeded in catalytic hydrodefluorination reactions lower fluorinated aryl fluorides molecular hydrogen sodium tert-butoxide as a base. Effects (i) ligand variation, (ii) mono- vs nuclearity, (iii) Ir Rh metal identity rationalized en route to achieve an effective hydrodefluorination.
