Tetraethylammonium bromide (TEAB) catalyzes the synthesis of thioesters by the oxidative coupling of aldehydes or alcohols with thiols or disulfides.[1]
It is used as a catalyst, along with o-iodoxybenzoic acid (IBX), in the oxidation of sulfides to sulfoxides[2] and primary carboxamides to one-carbon dehomologated nitriles.[3]
TEAB can also be used as an organic template to synthesize zeolite beta.[4]

Metal-organic frameworks (MOFs) with accessible Lewis acid sites are finding increasing application in the field of heterogeneous catalysis. However, the structural instability of MOFs when they are exposed to high temperature and/or high pressure often limits their applicability. In this
o-Iodoxybenzoic acid-and tetraethylammonium bromide-mediated oxidative transformation of primary carboxamides to one-carbon dehomologated nitriles.
