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.

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.
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)

Features and Benefits

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.
