Abstract

In situ switching of the associated anions of a rotaxane catalyst between Cl^- and TFPB^- exposes its dialkylammonium and imidazolium stations, respectively, thereby selectively catalyzing the reactions of a mixture of trans-cinnamaldehyde and an aliphatic thiol to yield the Michael adduct and the thioacetal product, respectively.
