Description and Uses

• Tetraethylammonium bromide (TEAB) catalyzes the synthesis of thioesters by the oxidative coupling of aldehydes or alcohols with thiols or disulfides.
• It is used as a catalyst, along with o-iodoxybenzoic acid (IBX), in the oxidation of sulfides to sulfoxides and primary carboxamides to one-carbon dehomologated nitriles.
• TEAB can also be used as an organic template to synthesize zeolite beta.
