Abstract
2,5-Dimethylfuran (DMF) is one of the most actively pursued biomass-derived chemicals due to the fact that it can serve both as a biofuel and an intermediate for drop-in terephthalate polymers. DMF can be accessed via catalytic hydrogenation of 5-(hydroxymethyl)furfural (HMF), but the difficult accessibility of HMF from cellulosic biomass is a major impediment to the commercial development of such a process. Alternatively, 5-(chloromethyl)furfural (CMF) is freely accessible in high yield directly from raw biomass and is shown here to be efficiently reduced to DMF under mild conditions via simple derivatives (aldimine, acetal).
