The Uses of Tetrabutylammonium tribromide

  1. Tetrabutylammonium tribromide (TBATB) is a salt of the lipophilic tetrabutylammonium cation and the linear tribromide anion. It is used as a phase transfer catalyst in organic synthesis as well as a mild brominating agent. A wide range of O-isopropylidene derivatives can be prepared from the sugars and their derivatives on reaction with acetone at room temperature by employing 2 mol % of tetrabutylammonium tribromide as a catalyst. Good yields, low catalyst loading, mild reaction conditions, and a non-aqueous workup procedure are some major advantages of this protocol.
  2. Tetrabutylammonium tribromide as an efficient generator of HBr for an efficient chemoselective reagent for acetalization of carbonyl compounds.

  3. It is sometimes used as a reagent used in organic synthesis as a conveniently weighable, solid source of bromine.
  4. Tetra-n-butylammonium tribromide is useful for the preparation of vicinal dibromides from alkenes and alkynes and alfa-bromo acetals.
  5. it is utilized to generate hydrogen bromide, which is used as an efficient chemoselective reagent for acetalization of carbonyl compounds.

The Uses of Tetrabutylammonium tribromide

Tetrabutylammonium Tribromide is used in the synthesis of antimicrobial agents via chalcones. Also used in the synthesis of potent tubulin polymerization inhibitors.
