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.
For general uses, product is also available in powdered form (198323)

특징 및 장점

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
