Redox Behavior and Catalytic Oxidation Reactions of Alcohols by a New Ruthenium(III)-Dioxolene-Amine Complex of Bis(2-pyridyl-methyl)-2-aminoethylamine

摘要

A ruthenium-dioxolene-amine complex,[Ru~(III)(NH_2-L)(Bu_2sq)](PF_6)_2 centre dot 0.5H_2O (NH_2-L = bis(2-pyridylmethyl)-2-aminoethylamine,Bu_2sq~- = 3,5-di-tert-butylsemiquino-nate),was newly prepared.The complex undergoes spontaneous one-electron reduction under basic conditions in MeOH and works as an electrocatalyst in the oxidation of benzyl alcohol to benzaldehyde under electrolysis at +0.4 V (vs SCE).
