Introduction
Tetra-n-butylammonium tribromide (TBATB) is one of the most widely used organic ammonium tribromides (OATB’s) for bromination [1-3] of several organic substrates.
Because it is a stable crystalline solid, easy to handle and maintains the desired reaction stoichiometry it is looked at as a substitute of Br2. It can also be considered as a ‘greener’ brominating agent [4] as well as an in situ generator of anhydrous HBr.
Other types of reactions like acylation, oxidation and protection/deprotection of several functional groups can be performed with TBATB in catalytic amounts and under solvent-free conditions.
