Indium (III) Bromide

Indium(III) Bromide Description

Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications. Bromide in an aqueous solution can be detected by adding carbon disulfide (CS2) and chlorine.

Indium (III) bromide, or indium tribromide, is an inorganic compound with the chemical formula InBr3. It has the same crystal structure as aluminum trichloride, with 6 coordinate indium atoms. When molten, it is the dimeric In2Br6, and it is predominantly dimeric in the gas phase. The dimer has bridging bromine atoms with a structure similar to dimeric aluminum trichloride Al2Cl6.

Indium(III) bromide is used in organic synthesis as a water tolerant Lewis acid. It efficiently catalyzes the three-component coupling of β-keto esters, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones. It is used as a catalyst to produce dithioacetals when unactivated alkynes react with thiols and fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium in high-performing solar cells.
