General description

Potassium carbonate is an inorganic base.[1] It participates as a base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene.[2] Addition of amino acids (glycine, sarcosine and proline) to K2CO3 (solvent) promotes the absorption of CO2.[3]

Application

Potassium carbonate may be used in the following processes:
  • As a reagent in the synthesis of polysubstituted iodobenzene derivatives.[4]
  • As a base for the Suzuki coupling of aryl halides with aryl boronic acids.[5]
  • The Heck reaction of styrene and bromobenzene.[1]
  • Preparation of disulfonated bis[4-(3-aminophenoxy)phenyl]sulfone, a disulfonated diamine monomer.[6]

    The cobalt-catalyzed Diels-Alder reaction of trimethylsilyl-substituted alkynes with 1,3-dienes led to dihydroaromatic intermediates which were transformed into iodobenzene derivatives. For this transformation, the dihydroaromatic intermediates had to be oxidized and the trimethylsilyl-substituted arene had to undergo a silicon-iodine exchange reaction.
