Abstract

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 ...
