title: Bis-sulfonic acid ionic liquids for the conversion of fructose to 5-hydroxymethyl-2-furfural.
abstract: Homogenous bis-sulfonic acid ionic liquids (1 mol equiv.) in DMSO  (10 mol equiv.) at 100 &#176;C efficiently mediated the conversion of D-fructose into  5-hydroxymethyl-2-furfural in 75% isolated yield, which was roughly a 10% increment compared to the case of the mono-sulfonic acid ionic liquids.
