Most 1-bromoalkanes are prepared by free-radical addition of hydrogen bromide to the 1-alkene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo derivative. [2] 1-Bromohexane undergoes reactions expected of simple alkyl bromides. It can form Grignard reagents. [3]
Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. [3]Bromobenzene is used to introduce a phenyl group into other compounds.
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, [1] and textiles.
1-Bromobutane is the precursor to n-butyllithium: [4] 2 Li + C 4 H 9 X → C 4 H 9 Li + LiX where X = Cl, Br. The lithium for this reaction contains 1-3% sodium. When bromobutane is the precursor, the product is a homogeneous solution, consisting of a mixed cluster containing both LiBr and LiBu.
21% of Americans have chronic pain. A new study found that diets rich in vegetables, fruits, grains, lean proteins, and dairy was linked to less chronic pain.
Reindeer can reach a running speed of almost 50 miles per hour(80 km), though most recorded speeds are between 25 and 35 miles per hour (40-56 km), which is still quite impressive.
If it works, just one 100ml bottle will be offered for sale on Earth at 100 million yen, or about $653,000. A standard serve is 80ml, making it one very expensive drink.
Petrofina's U.S. subsidiary, Fina Inc., announced that it would move its headquarters to Houston from Plano, Texas in 2000. Fina Inc. planned to occupy 149,000 square feet (13,800 m 2) in the World Houston Plaza building, near George Bush Intercontinental Airport.
