Tetraethylammonium bromide, reagent, 99%

Tetraethylammonium bromide (TEAB) catalyzes the high-yield oxidation of organic sulfides to sulfoxides by o-iodoxybenzoic acid (IBX) in chloroform/water at room temperature. TEAB has been used for the in situ preparation of tetraethylammonium superoxide from potassium superoxide for the conversion of primary alkyl halides to dialkyl peroxides.
