Tetraphenylphosphonium Bromide CAS 2751-90-8
Tetraphenylphosphonium bromide is a phase transfer catalyst, and its application is a new technology developed in the past two decades. It overcomes the disadvantage of requiring polar aprotic solvents in heterogeneous organic synthesis, and can make heterogeneous reactions proceed under relatively mild conditions, thus accelerating the reaction rate and improving the yield, thus playing a great role in promoting the development of organic synthesis.

1. Organic synthesis catalysts
Phase transfer catalysis (PTC): As an efficient phase transfer catalyst, it promotes ion transfer between the aqueous phase and the organic phase, significantly improves the rate and yield of heterogeneous reactions, and is widely used in drug synthesis (such as sulfonylation, dehydration reaction) and pesticide intermediate preparation.
Nucleophilic reagent: Generates alkyl bromide ions, participates in reactions such as acyl substitution and etherification, and simplifies the synthesis path of complex molecules (such as dyes and polymer monomers).
2. Materials Science
Electrolyte for energy devices: Due to its high ionic conductivity, it is used as a supporting electrolyte for fullerene electroreduction to improve the charge and discharge efficiency of batteries and supercapacitors.
Polymer modifier: Introduces bromine/phosphorus atoms into polymer chains such as polyethylene and polyvinyl chloride to enhance the thermal stability, mechanical strength and flame retardant properties of the material.
3. Pharmaceutical research and development
Drug intermediates: Participates in key steps such as ketone dehydration and catalytic hydrogenation, and is used to synthesize high-purity drug molecules (such as anticancer agents and antibacterial drugs) to reduce production costs.
4. Preparation of functional materials
Ionic liquid precursors: Synthesis of ionic liquids with low volatility and high thermal stability for use in green solvents and electrochemical catalysis.
