NHC‐Capped Cyclodextrins (ICyDs): Insulated Metal Complexes, Commutable Multicoordination Sphere, and Cavity‐Dependent Catalysis1. Issue 28 (3rd June 2013) - Guitet, Maxime
Abstract Don't slam the door! Cyclodextrins capped with an N‐heterocyclic carbene (ICyDs) entrapped metal ions within their cavity through a novel set of interactions, including X⋅⋅⋅π, which enabled the cavity to be closed by ligand exchange (see scheme; Bn=benzyl). Although insulated from an electrode, the deeply buried metal ions retained catalytic activity. The cavity influenced the regio‐ and stereochemical outcome of the catalyzed reactions.
