Application

Promotes the efficient O-alkylation of alcohols to form mixed alkyl carbonates.

Cesium carbonate, an alkali metal carbonate, is a commonly used inorganic base in organic reactions.Synthetic applications: As a catalyst to synthesize quinazoline-2,4(1H,3H)-diones from substituted 2-aminobenzonitriles and carbon dioxide.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.In combination with alkyl halide and acetonitrile, it forms an effective system for the alkylation method of phenols.

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.
