Abstract
|
A simple and mild procedure for the conversion of anilines into aryl isocyanates is described using 3-hydroxypropylammonium acetate (HPAA) ionic liquid as a novel and efficient media has been explored in the synthesis of aryl isocyanates from the reaction of substituted urea with sodium nitrite in a water immiscible solvent. This ionic liquid can be easily recovered and reused for several times without noticeable loss of activity.
