| Application: | Cesium fluoride can be used as: • A base in the Suzuki cross-coupling synthesis of ortho-substituted biaryls. • A reagent for the nucleophilic fluorination of primary halides and sulfonates in protic media such as tert-butyl and tert-pentyl alcohols. |
| Application: | Reactant for: • Preparation of building blocks for synthesis of fluoroallylic compounds • Synthesis of alcohols via hydrolysis of alkyl silyl ethers at neutral pH in buffered mixed organic-aqueous solutions • Nucleophilic fluorination of alkynyliodonium salts to form fluorovinylic compounds • Nucleophilic aromatic substitution (SNAr) reactions |
| Application: | Used in the successful synthesis of a single-crystal Dion-Jacobson phase, CsLaTa2O7, that has applications in photocatalysis and superconductivity. |
| General description: | Cesium fluoride is an inorganic compound known to be a source of fluoride ion and a catalyst in organic synthesis. 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. |
