Description and Uses

Cesium carbonate is a basic carbonate and is used in organic synthesis as a mild inorganic base. It can be used in C, N, O alkylation and arylation reactions. Cesium carbonate not only promotes the carbonylation of alcohols and carbamination of amines but also inhibits side reactions common in other processes. It is also used in six-membered annulation, intramolecular and intermolecular cyclizations, Suzuki coupling, aza-Henry, nucleophilic substitution, cross-coupling and different cycloaddition reactions.

Cesium carbonate is a versatile reagent for organic synthesis. This inorganic base has been employed in numerous organic applications ranging from N-protection of amino acids to a base in either the Horner- Wadsworth-Emmons reaction or in Suzuki couplings. It has also found use as a catalyst for ethylene oxide polymerization, in coating for spatter-free welding of steel in CO2, as a functional interlayer in photovoltaic devices and in oxide cathodes. Cesium carbonate is also used in the beer-brewing industry to make the "head" of beer foamier.
