Application

Tetraethylammonium bromide may be used:
  • As an organic template for synthesizing zeolite beta via hydrothermal crystallization.
  • As a catalyst for the oxidative coupling of aldehydes or alcohols with thiophenols or disulfides to form thioesters.
  • In combination with o-iodoxybenzoic acid (IBX) for the oxidative dehomologation of primary carboxamides to nitriles and α,α-disubstituted acetamides to ketones. This reagent combination can also be used for the conversion of sulfides to sulfoxides and N,N-disubstituted glycylamides into corresponding cyanamides.
