Unusual Ru(III) Chloro Complexes Containing Bis-dentate Ligands

摘要

Redox chemistry of oxo and nitrido Ru or Os complexes containing polypyridine, Schiff base, or porphyrin ligands has been extensively studied. Especially the polypyridyl complexes of ruthenium have been known as excellent photosensizers in the use of photovoltaic cells based on nanocrystalline TiO2 films as well.2 Multiple bonding with O and/or N atoms of the oxoitrido ligands bonded to the metal stabilizes oxidants and promotes the conversion of organic and inorganic substrates via electron transfer, oxygen or nitrogen atom transfer, hydride transfer, and proton-coupled electron transfer pathways. Many researchers have endeavored to find out other sources of chelating ligands. We have been developed the synthetic chemistry of the reactive complexes of the diphosphine ligands coordinated to the ruthenium metal.
