Revisit of Unusual Ruthenium(III) Dichloro Complex

摘要

Diverse oxidation chemistry associated with polypyridyl ruthenium complexes emerged. Especially oxo-metal reagents in high oxidation state have been found to be versatile stoichiometric and/or catalytic oxidants toward a variety of organic and inorganic substrates via electron transfer, oxygen atom transfer, hydride transfer, and proton-coupled electron transfer pathways. Among multiple ruthenium species appeared in the syntheses and mechanistic studies, Ru(III) complex is quite interesting material to investigate. However, there is a complication since Ru(III), once formed, undergoes disproportionation reaction to give Ru(II) and Ru(IV).
