一般描述

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.

应用

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.
