설명

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.
