Cesium fluoride 2N-3N
Application
Being highly dissociated, Cesium fluoride is a more reactive source of fluoride than related alkali metal salts. CsF is an alternative to tetra-n-butylammonium fluoride (TBAF) and TAS-fluoride (TASF).
Cesium fluoride is an inorganic compound that is a source of fluoride ions and a catalyst in organic synthesis. It is used in many organic reactions, such as 1,4− elimination, desilicylation, transesterification, acylation, nuclephilic aromatic substitution, etherification, and cross-coupling reactions.
Basic information
Caesium fluoride (cesium fluoride in American English) is an inorganic compound with the formula CsF. A hygroscopic white salt, caesium fluoride is used in the synthesis of organic compounds as a source of the fluoride anion.[5] The compound is noteworthy from the pedagogical perspective as caesium also has the highest electropositivity of all commonly available elements and fluorine has the highest electronegativity.
As with other soluble fluorides, CsF is moderately basic, because HF is a weak acid. The low nucleophilicity of fluoride means it can be a useful base in organic chemistry. CsF gives higher yields in Knoevenagel condensation reactions than KF or NaF.
