Abstract
AbstractThe copper‐catalyzed azide–alkyne cycloaddition reaction was used for the preparation of a series of bis‐ and tris‐3‐ and 24‐5β‐cholanetriazolyl derivatives of phosphorus acids, which contained anion‐binding triazolium sites and hydrophobic cholane residues. The influence of the location of the triazolium moiety (in 3α‐, 3β‐position) on fluoride‐ion complexation was investigated. The anion‐binding properties of tris(triazolium) ligands were studied for a series of inorganic and organic anions and high complexation constants were observed with fluoride, hydrosulfate, and benzoate anions.
