Abstract: | A rotaxane‐based Au catalyst was developed and the effect of the mechanical bond on its behavior was studied. Unlike the non‐interlocked thread, the rotaxane requires a catalytically innocent cofactor, the identity of which significantly influences both the yield and diastereoselectivity of the reaction. Under optimized conditions, AuI (the catalyst), AgI (to abstract the Cl? ligand), and CuI (the cofactor) combine to produce a catalyst with excellent activity and selectivity. |
