Ionic Liquid assisted efficient synthesis of some 2-aminobenzenethiols has been reported using three different Ionic Liquids (ILs) namely methylimidazolium tetrafluoroborate [MIM]+[BF4]−, methylimidazolium chloride [MIM]+[Cl]− and methylimidazolium nitrate [MIM]+[NO3]−. A comparative study has been carried out for the synthesis of target molecules in the presence and absence of IL, leading to conclusion that maximum yield has been observed with [MIM]+[BF4]−.

The Cost

The preparation of 5-hydroxymethylfurfural (5-HMF) through the dehydration of fructose with room temperature ionic liquids (ILs) has received much attention as a way of producing liquid fuels from renewable resources, but the cost of the process is considerably increased with IL as a solvent rather than as a catalyst. In this work, we have shown that the alkaline Ionic Liquid, 1-Butyl-3-methylimidazolium Hydroxide ([BMIM]OH), can be used as a catalyst in the conversion of fructose to 5-HMF. The maximum yield of 5-HMF was 91.6% at 160 °C after 8 h using dimethylsulfoxide (DMSO) as solvent, and the ketose is more easily dehydrated than aldose in this catalyst system.
