A new and efficient method of conjugate hydrothiocyanation of chalcones along with the preparation of a probe for demonstrating the utility of the resulting β-thiocyanato ketones in heterocyclic synthesis is reported. Chalcones undergo an efficient conjugate hydrothiocyanation with the task-specific ionic liquid (TSIL), 1-n-butyl-3-methylimidazolium thiocyanate ([bmim]SCN) followed by reaction with
