An Anion‐Switchable Dual‐Function Rotaxane Catalyst

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...

Description
Summary: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.
