Lignocellulosic biomass is a plentiful and renewable resource for fuels and chemicals. Despite this potential; nearly all renewable fuels and chemicals are now produced from edible resources; such as starch; sugars; and oils; the challenges imposed by notoriously recalcitrant and heterogeneous lignocellulosic feedstocks have made their production from nonfood biomass inefficient and uneconomical. Here; we report that N; N-dimethylacetamide (DMA) containing lithium chloride (LiCl) is a privileged solvent that enables the synthesis of the renewable platform chemical 5-hydroxymethylfurfural (HMF) in a single step and unprecedented yield from untreated lignocellulosic biomass; as well as from purified cellulose; glucose; and fructose. The conversion of cellulose into HMF is unabated by the presence of other biomass components; such as lignin and protein. Mechanistic analyses reveal that loosely ion-paired halide ions in DMA-LiCl are critical for the remarkable rapidity (1-5 h) and yield (up to 92%) of this low-temperature (≤140 °C) process. The simplicity of this chemical transformation of lignocellulose contrasts markedly with the complexity of extant bioprocesses and provides a new paradigm for the use of biomass as a raw material for a renewable energy and chemical industries. © 2009 American Chemical Society;
