Usage

Description

Cerium(III) chloride heptahydrate is a colorless crystalline solid that acts as a mild Lewis acid. It is known for its participation in various organic synthesis reactions, such as the allylation of aldehydes and Michael-type additions. It is also used as a reducing agent in place of sodium borohydride and as an efficient catalyst in certain reactions.

Uses

Used in Organic Synthesis:
Cerium(III) chloride heptahydrate is used as a reducing agent for the conversion of esters to allylsilanes in organic synthesis. It serves as an alternative to sodium borohydride, providing a milder and more selective reduction process.
Used in the Luche Reduction:
In the Luche reduction, cerium(III) chloride heptahydrate is used to selectively produce allylic alcohols from ketones, such as carvone, making it a valuable tool in the synthesis of complex organic molecules.
Used in the Synthesis of 2-Quinolones:
Cerium(III) chloride heptahydrate acts as a catalyst in the solvent-free microwave-assisted synthesis of 2-quinolones via the condensation of α-ketoesters with o-anilinoketones. This application demonstrates its versatility in promoting various organic reactions.
Used in the Beckmann Rearrangement:
When coupled with NaI, cerium(III) chloride heptahydrate promotes the Beckmann rearrangement of oximes, further showcasing its utility in organic chemistry.
Used in Michael-Type Addition:
Cerium(III) chloride heptahydrate, in combination with sodium iodide supported on silica gel, efficiently promotes the Michael addition of 1,3-dicarbonyl compounds to α,β-unsaturated ketones and α,β-unsaturated aldehydes. This application highlights its role as an effective catalyst in enhancing the reactivity of certain organic reactions.
