The first example of Sc(OTf)(3)-catalyzed sulfenylation of sodium sulfinates with N-(organothio)succinimides in ionic liquids (ILs) and water cosolvent system was developed, achieving thiosulfonates in moderate to excellent yields. Additionally, Sc(OTf)(3)/ILs could be recovered easily after the reactions and reused without a significant loss in the catalytic activity. Thus, the present protocol represents an interesting complement to known methods for thiosulfonates synthesis. (C) 2012 Elsevier Ltd. All rights reserved.
