Abstract A convenient and facile method for Michael addition of methyleneactivecompounds to chalcones has been developed by using 1,8-diazabicyclo [5.4.0]undec-7-ene- derived task-specific ionic liquids as reaction medium in the absence of any catalyst. This protocol could afford the Michael adducts in good to excellent yields in a short time, the workup is very simple, and the ionic liquid could
