Synthesis of β-keto-sulfones using ionic liquid [TPA][Pro] as an efficient and reusable reaction medium

Facile and an efficient synthesis of β-keto-sulfones is described by the reaction of α-haloketone with sodium alkyl/aryl sulphinates in ionic liquid [TPA][Pro] as an efficient and reusable reaction medium to afford the corresponding β-keto-sulfones in excellent yields.
