An enzyme mimic ammonium polymer as a single catalyst for glucose dehydration to 5-hydroxymethylfurfuralElectronic supplementary information (ESI) available: Details of experiments and computational study. See DOI: 10.1039/c4gc02488e

An ammonium resin (PBnNH 3 Cl) was used as a single catalyst for the glucose and polysaccharide dehydration to 5-hydroxymethylfurfural (HMF) in high selectivity (>80%) in a DMSO or biphasic reaction system. The isomerization mechanism was also studied by using the DFT computational method.
