General description
Potassium acetate is a hygroscopic material used as a base in organic synthesis. It can also be used as a buffer and neutralizing agent.
Application
Potassium acetate can be used:
Potassium acetate can also be used as a base:
- As a catalyst in the glycolysis of rigid polyurethane (PU) using DEG (diethylene glycol) as a solvent.
- As a nucleophilic catalyst for addition and polymerization reaction.
- As a nucleophilic catalyst in the regioselective reaction of epoxides with S-phenyl thioesters.
- As a promoter/base in transition metal-catalyzed reactions.
- As a source of methyl radical in photo-decarboxylative nucleophilic additions to phthalimides and source of potassium ion for templating reactions.
Potassium acetate can also be used as a base:
- In the Lossen rearrangement of hydroxamic acid.
- In the E2 elimination′s reaction.
- In the fragmentation of α,α-dichloroketoesters and deprotonation of alcohols.
