Laughrey, Z. R.; Upton, T. G.; Gibb, B. C. A deuterated deep-cavity cavitand confirms the importance of C–H⋯X–R hydrogen bonds in guest binding. Chem. Commun. 2006, 970-972.
Abstract
A deuterated cavitand host was examined for its affinity to a series of guests; for halogenated, preorganized guests binding was significantly stronger than the corresponding protium host.
