Star-like polyionic heterogeneous nanocatalyst as a highly active catalyst for promotion of Baylis–Hillman reaction in [bmim]Cl

The use of star-like polyionic Lewis base heterogeneous nanocatalyst for the Baylis–Hillman reaction of benzyl- and methylacrylates with aryl aldehydes has been investigated. The corresponding Baylis–Hillman adducts are obtained in good to high yields in one-pot procedure at room temperature in 5.5–8 h. The catalyst can be easily recovered with excellent purity by filtration and can be reused directly without any change in its catalytic activity.
