Aluminium bromide is any chemical compound with the empirical formula AlBrx. The species called "aluminium tribromide," is the most common aluminium bromide. The species aluminium monobromide forms from the reaction of HBr with Al metal at high temperature. It disproportionates near room temperature:

Antimony tribromide (SbBr3) is a chemical compound. It can be added to polymers such as polyethylene as a fire retardant.

Arsenic tribromide is the chemical compound with the formula AsBr3. This pyramidal molecule is the only known binary arsenic bromide. It forms by the direct reaction of bromine and arsenic. AsBr3 is noteworthy for its very high refractive index of approximately 2.3.

Phase transfer catalysis (PTC)' methodology is a powerful tool improving process efficiency, product selectivity and providing mild reaction conditions in organic chemical reactions. In many chemical reaction situations, there are different species (immiscible liquids or solid and liquid) which don't react each other due to separation by an interface.

Boron tribromide, BBr3, is a colorless, fuming liquid compound[1] containing boron and bromine. It is usually made by heating boron trioxide with carbon in the presence of bromine: this generates free boron which reacts vigorously with the bromine. It is very volatile and fumes in air because it reacts vigorously with water to form boric acid and hydrogen bromide.

IBr3 is the formula for iodine tribromideThe iodine converts to an I, while the Bromide becomes Br, and the prefix tri becomes a three after Br.

Nitrogen tribromide is a chemical compound with the formula NBr3. It is extremely explosive in its pure form, even at −100°C, and was not isolated until 1975.[2] It is a deep-red, volatile solid, and was first prepared by the bromination of bistrimethlysilylbromamine with BrCl at −87°C:

Phosphorus tribromide is a colourless liquid with the formula pbr3. It fumes in air due to hydrolysis and has a penetrating odour. It is widely used in the laboratory for the conversion of alcohols to alkyl bromides.
