Caesium fluoride Usage And Synthesis

Description

Caesium fluoride can be used as an analytical reagent, and also for the manufacture of optical crystals
It can be used for the preparation of fluorinated isocyanate.
During the Suzuki cross-coupling synthesis reaction, it can be used as a base for the positive substitution of the biaryls compound; it can also be used as a nucleophile for the fluorination of protic mediate such as the halide and sulfonate contained in tert-butyl alcohol or t-amyl alocohol. It can also be used as catalyst for the Silyl enol ether reaction of carbonyl compounds; used for efficient synthesis of single crystal Dion-Jacobson phase CsLaTa2O7 tto be applied to photocatalytic and superconductivity.

Chemical Properties

white crystalline powder

Uses

Used as a base in a Suzuki cross-coupling synthesis of ortho-substituted biaryls.5 Also employed as a reagent for nucleophilic fluorination of primary halides and sulfonates in protic media such as tert-butyl and tert-pentyl alcohols.6

Uses

A preperation of building block for synthesis of fluoroallylic compounds.

Uses

Catalyst in oxidation reactions; as a solid base when adsorbed onto Celite, q.v. Fluoride source in organic synthesis. Inorganic scintillator.

Hazard

A poison.

Safety Profile

A poison. Incompatible with benzenediazonium tetrafluoroborate and difluoroamine. When heated to decomposition it emits toxic fumes of F-.

Purification Methods

Crystallise it from aqueous solution by adding ethanol.
