Tetraethylammonium bromide is used as a phase transfer catalyst. It acts as a source of tetraethylammonium ions in pharmacological and physiological studies. It is also employed in organic chemical synthesis. It plays a major role in the preparation of tetraethylammonium superoxide from potassium superoxide for the conversion of primary alkyl halides to dialkyl peroxides. Furthermore, It is utilized as a catalyst in the oxidation of organic sulfide to sulfoxide using o-iodoxybenzoic acid.
Phase-transfer catalyst; see Appendix 2.
For use in combination with anhydrous HBr as a reagent for selective monohydrobromination of an alkyne, see: Org. Synth., 76, 263 (1998).
