Selective Oxidation of 5-Hydroxymethylfurfural to 2,5-Diformylfuran by

Hydroxymethyl-2-furfural (HMF) was selectively converted to 2,5-diformylfuran (DFF) under mild conditions by polymer-supported IBX amide reagent, thus providing a new plat- form for the production of highly valuable chemicals from biomass.
