Phosphorus tribromide, like PCl 3 and PF 3, has both properties of a Lewis base and a Lewis acid. For example, with a Lewis acid such as boron tribromide it forms stable 1 :1 adducts such as Br 3 B · PBr 3. At the same time PBr 3 can react as an electrophile or Lewis acid in many of its reactions, for example with amines.
Boron tribromide is commercially available and is a strong Lewis acid.. It is an excellent demethylating or dealkylating agent for the cleavage of ethers, also with subsequent cyclization, often in the production of pharmaceuticals.
Tribromide is the anion with the chemical formula Br 3 −, or salts containing it: . Tetrabutylammonium tribromide; Tetrabromophosphonium tribromide; Pyridinium perbromide; Sodium and potassium tribromides can be prepared by reacting NaBr or KBr with aqueous bromine.

Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

Aluminium tribromide is the most common form of aluminium bromide. [3] It is a colorless, sublimable hygroscopic solid; hence old samples tend to be hydrated, mostly as aluminium tribromide hexahydrate (AlBr 3 ·6H 2 O).
Nitrogen tribromide reacts instantly with ammonia in dichloromethane solution at −87 °C to yield NBrH 2. [7] NBr 3 + 2 NH 3 → 3 NH 2 Br. It also reacts with iodine in dichloromethane solution at −87 °C to produce NBr 2 I, which is a red-brown solid that stable up to -20 °C. [7] NBr 3 + I 2 → NBr 2 I + IBr
