일반 설명
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.
애플리케이션
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.

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
