Abstract 1-Methylimidazolium trifluoroacetate ([Hmim] TFA) is reported as a cost-effective catalyst for a simple and environmentally benign hetero-Michael reaction.[Hmim] TFA works both as reaction medium and catalyst. The reaction is applicable to various aromatic sulfur and nitrogen nucleophiles. This method has advantages such as high yields, short reaction time, and simple workup. The catalyst could be recycled several times without any loss of ...
