Description
- General description: Cesium carbonate is an inorganic base generally used in C, N, O-arylation and alkylation reactions. It is also used in six-membered annulation, cross-coupling, intramolecular and intermolecular cyclizations, aza-Henry reaction, Horner-Emmons cyclization, and cycloaddition reactions.[1][2]
- Application: Cesium carbonate, an alkali metal carbonate, is a commonly used inorganic base in organic reactions.[3]Synthetic applications: As a catalyst to synthesize quinazoline-2,4(1H,3H)-diones from substituted 2-aminobenzonitriles and carbon dioxide.[4]As a base to synthesize cyclic carbonates using halo- or tosyl-alcohols and carbon dioxide in the absence of any transition metal or organo catalyst.[5]In combination with alkyl halide and acetonitrile, it forms an effective system for the alkylation method of phenols.[6]
