Potassium Trifluoromethanesulfonate
Potassium Trifluoromethanesulfonate (CAS: 2926-27-4), commonly called potassium triflate, is the potassium salt of triflic acid featuring the highly stable, weakly coordinating triflate anion. This white crystalline salt serves as a versatile reagent and electrolyte component in organic synthesis, electrochemistry, and advanced materials. In synthetic chemistry, it functions as a source of the triflate anion for preparing triflate esters and salts, as a mild base in transition metal catalysis, and as an additive that accelerates cross-coupling reactions. Its exceptional solubility in polar organic solvents and high thermal stability make it valuable as a supporting electrolyte in electrochemical cells and capacitor research. The compound also finds use in ionic liquid preparation and as a phase-transfer agent. With its predictable behavior and minimal nucleophilicity, potassium triflate is a dependable reagent for demanding synthetic and electrochemical applications.
– Cross-Coupling Catalysis: Used as an additive and triflate source in palladium-catalyzed coupling reactions including Suzuki, Stille, and Negishi transformations.
– Electrochemical Applications: Serves as a supporting electrolyte in non-aqueous batteries, supercapacitors, and electroanalytical systems requiring high ionic conductivity.
– Organic Synthesis: Applied in preparing triflate esters, triflate salts, and as a non-nucleophilic base in sensitive synthetic transformations.
– Ionic Liquid and Materials Research: Employed as a precursor for triflate-based ionic liquids and conductive polymer formulations.
