Tetrabutylammonium tribromide is a pale orange solid with the formula [N(C4H9)4]Br3. It is a salt of the lipophilic tetrabutylammonium cation and the linear tribromide anion. The salt is sometimes used as a reagent used in organic synthesis as a conveniently weighable, solid source of bromine.
The compound is prepared by treatment of solid tetrabutylammonium bromide with bromine vapor:
- [N(C4H9)4]Br + Br2 → [N(C4H9)4]Br3
