摘要

A selective electrochemical oxidation was developed under mild condition.Various mono-carbonyl and multi-carbonyl com-pounds can be prepared from different aromatic hydrocarbons with moderate to excellent yield and selectivity by virtue of this electrochemical oxidation.The produced carbonyl compounds can be further transformed into α-ketoamides,homoallylic alcohols and oximes in a one-pot reaction.In particular,a series of α-ketoamides were prepared in a one-pot continuous electrolysis.Mechanistic studies showed that 2,2,2-trifluoroethan-1-ol (TFE) can interact with catalyst species and generate the corresponding hydrogen-bonding complex to enhance the electrochemical oxidation performance.
