Abstract

Cyclodextrins (CDxs) have been selectively deuterated using a Ru/C-catalyzed H-D exchange reaction in D2O. The structures of the deuterated CDxs barely changed and their (1)H NMR spectra became very simple, which made it possible for the deuterated CDxs to be applied to the analysis of CDx complexes. Furthermore, the deuterated CDxs allowed for the existence of the equilibrium between free and complexed CDx to be confirmed, even at rt.
