Front Cover: Indirect Baeyer–Villiger Oxidation of Furfural by In Situ Formed HOBr in an Undivided Electrochemical Cell (ChemSusChem 3/2026)

The Front Cover shows a newly developed method that uses a simple undivided electrochemical cell to perform oxidative functionalization of renewable furfural by using an indirect Baeyer–Villiger-type oxidation. In this method, bromine gets electrochemically generated from bromide salt followed by the formation of hypobromous acid, which acts as an oxidant. The immediate consumption of hazardous bromine as it is generated allows its concentration to be kept very low. The obtained yields are comparable to those of existing thermochemical methods and allow (renewable) electricity to be used as a driving force.
