Boron tribromide, BBr 3, is a colorless, fuming liquid compound containing boron and bromine. Commercial samples usually are amber to red/brown, due to weak bromine contamination. It is decomposed by water and alcohols. [2]

2009年6月9日 · Boron tribromide is a chemical compound of boron and bromine. It is a commercially available strong Lewis acid. Boron tribromide is an excellent demethylating or dealkylating agent for ethers and is often used in the production of pharmaceuticals.

Boron tribromide (BBr 3) is a strong Lewis acid generally used as a reagent for the deprotection of ethers. Alkyl aryl ethers are cleaved at the alkyl-oxygen bond to give ArOH and alkyl bromides.

2024年12月3日 · Boron tribromide, often abbreviated as BBr3, is a chemical compound made up of one boron atom and three bromine atoms. Known for its powerful reactions, especially with water and alcohols, this colorless, fuming liquid plays a crucial role in organic synthesis and material science.

2025年1月27日 · Boron tribromide is a colourless, fuming liquid compound containing boron and bromine. It is usually made by heating boron trioxide with carbon in the presence of bromine: this generates free boron that reacts vigorously with the bromine.

BORON TRIBROMIDE strongly attacks wood and rubber with generation of flammable hydrogen gas. Reacts exothermically and violently with water. Mixing tungsten trioxide and boron tribromide caused an explosion when the reaction was not cooled in an ice bath.

Boron tribromide, BBr 3, is a liquid compound containing boron and bromine. It is usually made by heating boron oxide with carbon in the presence of bromine: this generates free boron which reacts vigorously with the bromine.

Boron tribromide (BBr3) is a Lewis acid commonly used for the demethylation of methyl ethers. Boron tribromide is available neat, but is often purchased as a 1M solution in either DCM , hexane , or heptane .

Boron tribromide is a strong Lewis acid generally employed in the deprotection of -OH and -NH groups. It is a moisture-sensitive liquid, which is also used to cleave esters or ethers into alkyl bromides.
