Description
General description
Potassium carbonate is an inorganic base.[5] It participates as a base in the palladacycle catalyzed Heck reaction of chlorobenzene with styrene.[3] Addition of amino acids (glycine, sarcosine and proline) to K2CO3 (solvent) promotes the absorption of CO2.[7]
Application
Potassium carbonate has been used in the preparation of disulfonated bis[4-(3-aminophenoxy)phe
It may be used in the following studies:
• As a reagent in the synthesis of polysubstituted iodobenzene derivatives.[1]
• As a base for the synthesis of high molecular weight homopolymers and copolymers derived from various bisphenols.[2]
• As a base for the Suzuki coupling of aryl halides with aryl boronic acids.[4]
• The Heck reaction of styrene and bromobenzene.[5]
