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.

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)phenyl]sulfone, a disulfonated diamine monomer.
