DPhSO is reported as an active and environmentally friendly solvent for synthesizing HMF from fructose, with nearly 100% conversion efficiency. The reaction mechanism of DPhSO-catalyzed HMF formation was analyzed through various experiments and theoretical calculations.
We report diphenyl sulfoxide (DPhSO) as an active, cheap and environmentally friendly solvent to facilely synthesize 5-hydroxymethylfurfural (HMF) from fructose. It acts as both the catalyst and solvent to afford nearly 100% conversion of fructose and 68.4% yield of HMF. In particular, HMF was easily extracted using water and DPhSO froze into an insoluble solid at low temperature. DPhSO was reused 6 times without significant loss of activity. The reaction mechanism of DPhSO-catalyzed HMF formation was analyzed by NMR and ESI-MS experiments and theoretical calculations.
