A simple method for the synthesis of β-CF3 ketones through copper/silver cocatalyzed oxidative coupling of enol acetates with ICH2CF3 has been developed. Enol acetates were chosen as the source of carbonyl group, giving the β-CF3 ketones in moderate yields. Control experiments imply that a radical process maybe involved in this reaction.

The efficient intermolecular alkoxylation reactions of various enolacetates and different alcohols are developed in the electrochemical process for the first time. Enolacetatesderivedfrom either aromatic, alkyl, or alicyclic ketones, and abundant free alcohols directly used in this synthetic strategy, make this transformation very valuable in synthesis and application in the future.

We have developed the synthesis of α-substituted ketone compounds with enol acetates in an electrochemical way. By using cheap NH4SCN and MeOH as the radical sources, a series of valuable α-thiocyanates/methoxy ketones were synthesized under mild electrolysis conditions in acceptable yields with diverse functional group compatibility. Additionally, the scale-up experiment and synthetic transformations
