Bimolecular nucleophilic substitution (SN2) is one of the most well-known fundamental reactions in organic chemistry to generate new molecules from two molecules. In principle, a nucleophile attacks from the back side of an alkylatingagent having a suitable leaving group, most commonly a halide. However, alkyl halides are expensive, very harmful, toxic and not so stable, which makes them problematic

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
