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 has been used in the preparation of disulfonated bis[4-(3-aminophenoxy)phenyl]sulfone, a disulfonated diamine monomer.
It may be used in the following studies:
As a Reagent in the synthesis of polysubstituted iodobenzene derivatives.
As a base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.
As a base for the Suzuki coupling of aryl halides with aryl boronic acids.
The Heck reaction of styrene and bromobenzene.
