文摘

Multiple deuterium exchange between DMSO-d₆ and amide hydrogens in two hexaamido cryptand fluoride receptors has been verified by ¹⁹F and ²H NMR and FAB mass spectral studies. Structural results for one of the complexes indicate a tricapped trigonal prism hydrogen bond coordination geometry around an encapsulated fluoride, with hydrogen bonds from fluoride to six amide and three phenyl hydrogens.
