A new type of electrochemical oxidation of alcohols mediated with a ruthenium–dioxolene–amine complex in neutral water
摘要:
Electrochemical oxidation of [Ru-II(terpy)(sq)(NH3)](+) in neutral water (pH 8.0) at +0.8 V (versus SCE) generated [Ru-II(terpy)(q)(NH2 center dot)](2+) and/or [Ru-III(terpy)(sq)(NH2 center dot)](2+) (terpy = 2,2':6',2 ''-terpyridine, sq = 3,5-di-tert-butyl-1,2-semiquinonate, q = 3,5-di-tert-butyl-1,2-benzoquinone), which played roles in hydrogen abstraction and one-electron acceptor in the catalytic oxidation of methanol, ethanol, and 2-propanol affording formaldehyde, acetoaldehyde, and acetone, respectively, under the electrolysis conditions.
