产品说明

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.
