3-Bromobenzyl bromide Chemical Properties,Usage,Production

Chemical Properties

White to yellow solid

Uses

3-Bromobenzyl bromide was used in the synthesis of, 1,7-di(3-bromobenzyl)cyclen and substituted 8-arylquinoline, phosphodiesterase 4 (PDE4) inhibitors.

Uses

3-Bromobenzyl bromide was used in the synthesis of:

  • 1,7-di(3-bromobenzyl)cyclen
  • substituted 8-arylquinoline, phosphodiesterase 4 (PDE4) inhibitors

General Description

3-Bromobenzyl bromide undergoes reduction with diethylzinc in the presence of Pd(PPh3)4 to yield corresponding hydrocarbon.

Synthesis

591-17-3

823-78-9

General procedure for the synthesis of 3-bromobenzyl bromide from 3-bromomethylbenzene: To a mixture of N-bromosuccinimide (NXS) and substrate (1 or 6) in acetonitrile (CH3CN), silicon tetrachloride (SiCl4) was slowly added at room temperature, and the reaction mixture was stirred continuously until thin-layer chromatography (TLC) monitoring showed complete disappearance of the feedstock. Subsequently, the reaction mixture was poured into water and extracted with dichloromethane (CH2Cl2). All organic phase extracts were combined and dried with anhydrous magnesium sulfate (MgSO4), followed by concentration under reduced pressure to remove the solvent. The residue was purified by recrystallization (petroleum ether-ether, 3:1) to give the pure products 2b-2g or 3b; or by silica gel column chromatography (hexane-ethyl acetate, 10:1 or 30:1) to give the pure products 2a, h, i, 3a-5 or 7-9.
