“…Accordingly, due to the fact that organic tribromides are able to release a stoichiometric amount of bromine, stable, and crystalline solids, they have received great attention in organic synthesis. [88,89] Over the past few years, many improved methods of organic ammonium ditribromides synthesis, as a brominating catalyst, have been reported, involving the oxidation of Br − to Br 3 − in efficient and environmentally benign manner. In this regard, In 2014, Dhar et al…”
