3,5-Dibromobenzyl bromide Chemical Properties,Usage,Production
Chemical Properties
white to beige-brownish powder
Uses
3,5-Dibromobenzyl bromide, is an important raw material and intermediateintermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.
Synthesis
145691-59-4
56908-88-4
Under argon protection, (3,5-dibromophenyl)methanol (5.00 g, 0.021 mol) was dissolved in anhydrous tetrahydrofuran (250 mL), and the solution was cooled to 0 °C. Lithium aluminum hydride (1.62 g, 0.043 mol) was added slowly and in batches, followed by stirring the reaction mixture at room temperature overnight. Upon completion of the reaction, it was carefully quenched with water, ether (100 mL) was added and acidified with concentrated hydrochloric acid solution until the solid residue was completely dissolved. The reaction mixture was extracted with ether, the organic phases were combined and dried over anhydrous magnesium sulfate. After filtration, the organic phase was concentrated under reduced pressure to give 4.31 g of the target product. The structure of the product was confirmed by nuclear magnetic resonance hydrogen spectroscopy (1H NMR, CDCl3): δ 1.34 (s, 18H, tert-butyl hydrogen), 4.70 (s, 2H, benzyl hydrogen), 7.23 (d, 2H, J = 1.8 Hz, aromatic hydrogens), and 7.38 (t, 1H, J = 1.8 Hz, aromatic hydrogens). The crude alcohol (4.25 g) was dissolved in anhydrous dichloromethane (500 mL) and cooled at 0 °C. Triphenylphosphine (10.23 g, 0.039 mol) and carbon tetrabromide (12.93 g, 0.039 mol) were added sequentially, and the reaction mixture was stirred at room temperature for 1 hour. After completion of the reaction, the reaction was quenched with water and extracted with dichloromethane. The organic phase was dried with anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The product was purified by fast column chromatography on silica gel using hexane as eluent to give 4.62 g (86% yield) of 1,3-dibromo-5-(bromomethyl)benzene.
