Abstract

The common Lewis acid SnCl₄ could efficiently convert glucose into 5-hydroxymethylfurfural in 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMim]BF₄). New evidence indicated that the formation of the five-membered-ring chelate complex of the Sn atom and glucose may play a key role for the formation of HMF, and the mechanism for the reaction was proposed. In addition, the [EMim]BF₄/SnCl₄ system was also suitable for the conversion of fructose, sucrose, inulin, cellobiose and starch.
