Bismuth(III) Bromide

Bismuth(III) bromide is a chemical compound with the formula BiBr3. It is a yellow solid that is insoluble in water but soluble in organic solvents such as ethanol and acetone.

The compound has a distorted trigonal prismatic structure, with each bismuth atom coordinated to six bromine atoms. It is a Lewis acid and can form complexes with Lewis bases.

Bismuth(III) bromide is primarily used in organic synthesis as a catalyst for various reactions, including Friedel-Crafts acylation, esterification, and alkylation. It can also be used in the production of other bismuth compounds, as well as in the manufacture of high-density liquids for precision engineering.

It is important to handle bismuth(III) bromide with care, as it is toxic if ingested or inhaled. Protective clothing and gloves should be worn when handling the compound, and it should only be used in a well-ventilated area.
