Gold(I) bromide - Wikipedia

Gold(III) bromide is a dark-red to black crystalline solid. It has the empirical formula AuBr3, but exists primarily as a dimer with the molecular formula Au2Br6 in which two gold atoms are bridged by two bromine atoms. It is commonly referred to as gold(III) bromide, gold tribromide, and rarely but traditionally … See more The first mention of any research or study of the gold halides dates back to the early-to-mid-19th century, and there are three primary researchers associated with the extensive investigation of this particular area of chemistry: … See more The most common synthesis method of gold(III) bromide is heating gold and excess liquid bromine at 140 °C: 2 Au + 3 Br2 → Au2Br6 Alternatively, the halide-exchange reaction of gold(III) chloride with hydrobromic acid has also been … See more Catalytic chemistry Gold(III) bromide is used as a catalyst in a variety of reactions, but one of its most interesting uses is found in the Diels-Alder reaction. Specifically, the compound catalyzes the reaction between an enynal unit and See more The dimer, digold hexabromide, has structural properties similar to those of the other gold trihalide dimeric compounds, such as gold(III) chloride.
