Phosphonium Ionic Liquid-Catalyzed Michael Addition of Mercaptans to [alpha],[beta]-Unsaturated Ketones

A clean and efficient Michael addition reaction on chalcones using phosphonium ionic liquid catalyst (PhosIL-Cl) is described. The method provides several advantages, such as simple workup, environmental friendliness, mild conditions, and excellent yields. In addition, the ionic liquid was chosen as...

Summary:A clean and efficient Michael addition reaction on chalcones using phosphonium ionic liquid catalyst (PhosIL-Cl) is described. The method provides several advantages, such as simple workup, environmental friendliness, mild conditions, and excellent yields. In addition, the ionic liquid was chosen as a green solvent, recovered, and reused several times in subsequent reactions.
