A new, highlyefficient, inexpensive, recyclable, mild, convenient, and green protocol for chemoselective aza/thia- Michaeladdition reactions of amines/thiols to α,β - unsaturated compounds using triethylammonium acetate ( TEAA ) ionic liquid was developed. The catalyst can be recycled ten times and obviate the need for toxic and expensive catalysts.
