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