WebJul 2, 2004 · Then boron tribromide (2.2 mL, 0.022 mole) in anhydrous benzene (5 mL) is added slowly over 30-40 min with stirring while the flask is cooled with ice. The solution obtained is stirred for one hour at room temperature and for 5-6 hours at 55-65°C with emission of hydrogen bromide. tiny scientist summer campBoron tribromide is commercially available and is a strong Lewis acid. It is an excellent demethylating or dealkylating agent for the cleavage of ethers, also with subsequent cyclization, often in the production of pharmaceuticals.
