Descripción

Descripción general

Potassium acetate is a hygroscopic material used as a base in organic synthesis. It can also be used as a buffer and neutralizing agent.

Aplicación

Potassium acetate can be used:

• 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.
