CERIUM(III) CHLORIDE HEPTAHYDRATE Usage And Synthesis

Chemical Properties

colourless crystalline solid

Uses

Cerium(III) chloride heptahydrate is used in the preparation of allylsilanes from esters. It is used as a reducing agent in organic synthesis in place of sodium borohydride. In Luche reaction, carvone gives selectively allylic alcohol.

Uses

Catalyst employed in a solvent-free microwave-assisted synthesis of 2-quinolones via condensation of ?-ketoesters with o-anilinoketones. Coupled with NaI promotes the Beckmann rearrangement of oximes.

Uses

Cerium(III) chloride heptahydrate can be used in the conversion of esters to allylsilanes.

Application

Cerium(III) chloride heptahydrate can be used:
As a precursor to prepare cerium oxide nanoparticles for biomedical applications and photocatalytic degradation.
As a solution to fabricate thin films of CeO2 on glass substrates by the spray pyrolysis process.
As a dopant to fabricate ZnO and CeO2 nanocrystals for electrochemical sensing of H2O2 and photocatalytic degradation of Rhodamine B and Congo red dyes.
As an additive to prepare corrosion-inhibiting formulations and coatings.
To synthesize carbon nanofiber composites to fabricate high-temperature polymer electrolyte membrane fuel cell cathodes.
As a support for the combination of cerium(III)chloride heptahydrate and sodium iodide supported on silica gel to promoteMichael-type additions. These catalysts are used to convert from indolesand nitroalkenes to 2-indolyl-1-nitroalkane derivatives in good yields.

General Description

Cerium(III) chloride heptahydrate is a mild Lewis acid. It participates in the allylation of aldehydes. Cerium(III) chloride heptahydrate in combination with sodium iodide supported on silica gel efficiently promotes Michael-type addition. Cerium(III) chloride heptahydrate in the presence of sodium iodide acts as an efficient catalyst for the Michael addition of 1,3-dicarbonyl compounds to α,β-unsaturated ketones and α,β-unsaturated aldehydes.
