Versatile, One-pot Introduction of Nonahalogenated 2-ammonio-decaborate Ions As Boron Cluster Scaffolds into Organic Molecules; Host-guest Complexation with γ-cyclodextrin

We report the modification of the 2-ammonio group at halogenated decaborate ions with 2,3-epoxypropane, the product of which reacts readily with nucleophiles to form previously inaccessible coupling of polyhedra with organic molecules and materials. We demonstrate that these ions present a good binding motif in supramolecular chemistry.
