Application: | Potassium carbonate may be used in the following processes: • As a reagent in the synthesis of polysubstituted iodobenzene derivatives. • As a base for the Suzuki coupling of aryl halides with aryl boronic acids. • The Heck reaction of styrene and bromobenzene. • Preparation of disulfonated bis[4-(3-aminophenoxy)phe |
General description: | Potassium carbonate is an inorganic base. It participates as a base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene. Addition of amino acids (glycine, sarcosine and proline) to K2CO3 (solvent) promotes the absorption of CO2. |
