Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Don't slam the door!</bold> 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.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg26mfw7cg" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
