With a pinch of salt: The association of NaBr as a catalyst and DMSO as a solvent allows the synthesis of 2,5-diformylfuran from 5-(hydroxymethyl)furfural (HMF) or fructose in 75 or 50 % yield, respectively. This transformation occurs through the formation of 5-(bromomethyl)furan-2-carbaldehyde followed by a Kornblum-type reaction.
