Ionic liquids (ILs) have been widely applied as catalysts, promoters and/or reaction medium in organic synthesis due to their non-flammability, low volatility, good solubility, readily tunable catalytic activities and good recyclability. Herein, the recent advances on the applications of acidic task-specific ionic liquids (TSILs), basic TSILs and chiral TSILs in Michael addition have been reviewed. Moreover, the structure, catalytic activity and probable reaction mechanism of ILs are also fully discussed. Contents
