Általános leírás
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.
Alkalmazás
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.
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
Used in the successful synthesis of a single-crystal Dion-Jacobson phase, CsLaTa2O7, that has applications in photocatalysis and superconductivity.
For general uses, product is also available in powdered form (198323)

Aprotic solvents are usually preferred for the SN2 reactions, because nucleophilicity and hence SN2 reactivity are severely retarded by the influence of the partial positive charge of protic solvents. In this work, we introduce a remarkable effect of using tertiary

Treatment of a benzyl substituted meso-ditriflate with boronic acids in the presence of palladium acetate, triphenylphosphine and caesium fluoride results in intermolecular Suzuki coupling followed by vinyl triflate-arene cyclisation to provide, in high yields, single regioisomers of tricyclic-carbocycles.

A highly efficient and rapid total synthesis of 9Z-retinoic acid was accomplished by caesium fluoride-promoted Stille coupling reaction; using a common building block, 9Z-retinoic acid analogues were also prepared by the same method without isomerisation of the Z-double bond.
