A metal-free TBHP-mediated radical alkylation of enolacetates with alcohols is described. This method provides a new route to a variety of β-hydroxy-ketones in moderate to good yields.

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 developed a method to synthesize fluorinated 1,4-unsaturated dicarbonyl compounds via photoredox catalyzed radical addition process. Commercially available ethyl bromodifluoroacetate (BrCF2CO2Et) as fluoroalkyl source, the corresponding fluoro-containing dicarbonyl compounds could be obtained in moderate to good yields.
