Caesium carbonate can also be used in Suzuki, Heck, and Sonogashira synthesis reactions. In the past Cr(VI) and Mn(VII) reagents have been used to oxidize alcohols, however, these reagents are toxic and comparatively expensive. The process of selective oxidation of alcohols to carbonyls had been quite difficult due to the nucleophilic character of the carbonyl intermediate.
There is no acid formation produced when primary alcohols are used. In the presence of sodium tetrachloroaurate (NaAuCl 4), caesium carbonate is very efficient mechanism for aerobic oxidation of different kinds of alcohols into ketones and aldehydes at room temperature without additional polymeric compounds. Research on these compounds has focused on their synthesis and biological activity. 2 CsOH + CO 2 → Cs 2CO 3 + H 2O Chemical reactions Ĭaesium carbonate facilitates the N-alkylation of compounds such as sulfonamides, amines, β-lactams, indoles, heterocyclic compounds, N-substituted aromatic imides, phthalimides, and other similar compounds. It can also be synthesized by reacting caesium hydroxide with carbon dioxide. Upon heating, caesium oxalate is converted to caesium carbonate with emission of carbon monoxide. It also appears to have applications in energy conversion.Ĭaesium carbonate can be prepared by thermal decomposition of caesium oxalate. This compound is used in organic synthesis as a base. Its solubility is higher in organic solvents compared to other carbonates like potassium and sodium carbonates, although it remains quite insoluble in other organic solvents such as toluene, p-xylene, and chlorobenzene.
Caesium carbonate has a high solubility in polar solvents such as water, alcohol and DMF. Caesium carbonate or cesium carbonate is a white crystalline solid compound.
