Abstract Sorbitol was effectively converted to isosorbide by treatment with [TMPA][NTf 2 ] in the presence of catalytic amounts of TsOH under microwave heating at 180 °C. The reaction completed within 10 min and isosorbide was isolated to about 60 %. Ionic liquids were readily recovered by an extraction treatment and reused several times.
