It has been used in many organic reactions like 1,4?elimination, desilylation, transesterification, acylation, nucleophilic aromatic substitution, etherification, cross?coupling reactions and so on.ĭecomposition it emits toxic fumes of F-.Ĭrystallise it from aqueous solution by adding ethanol. Caesium has the highest electropositivity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.Ĭesium fluoride is an inorganic compound known to be a source of fluoride ion and a catalyst in organic synthesis. Cesium fluoride can be used as a source of fluoride anion for organic synthesis. Used as a base in a Suzuki cross-coupling synthesis of ortho-substituted biaryls.5 Also employed as a reagent for nucleophilic fluorination of primary halides and sulfonates in protic media such as tert-butyl and tert-pentyl alcohols.6Ĭesium fluoride is an inorganic compound with the chemical formula CsF, which is a hygmoscopic white salt.
