Anion binding by neutral ferrocene-amide receptors

ANION BINDING BY NEUTRAL FERROCENE-AMIDE RECEPTORS [Pg.66]

Nature uses globular protein domains to bind sulfate and phosphate anions using respectively 7 and 12 complementary anion-hydrogen bond arrangements. With this in mind we decided to construct new, neutral ferrocene derivatives that contain various hydrogen bond donor and acceptor sites for anion recognition. [Pg.66]

Remarkable downfield shifts of the respective amide protons, ranging from A8 0.9 to 2.5 ppm, are exhibited by receptors [96]—[98] on addition of tetrabutylammonium dihydrogenphosphate, hydrogensulfate and chloride salts to deuteriated acetonitrile-DMSO solutions. The resulting [Pg.68]
