4-Cyanobenzyl bromide Chemical Properties,Uses,Production
Uses
4-Cyanobenzyl bromide is an important intermediate for pharmaceutical production. It can be used for the synthesis of a series of piperidine-linked aromatic diimidazolines, which have been synthesized as conformationally restricted congeners of the anti-Pneumocystis carinii (PCP) drug, Pentamidine.
Chemical Properties
4-Cyanobenzyl bromide (C8H6BrN, CAS registry No. 17201-43-3) is a white solid. Its melting point is 113-117°C, and flash point is 125.1°C. It is insoluble in water at 20°C. It is stable under normal temperatures and pressures. It should be stored at 0-5°C.
Chemical Properties
white to light yellow crystal powde
Uses
A benzyl halide as postemergence herbicides.
Uses
4-(Bromomethyl)benzonitrile is used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile. It is also useful in the preparation of 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile by reaction with 2H-tetrazole in the presence of potassium hydroxide.
Uses
4-(Bromomethyl)benzonitrile may be used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile.
General Description
4-(Bromomethyl)benzonitrile reacts with 2H-tetrazole in the presence of KOH to yield 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile.
Synthesis

874-89-5

17201-43-3
GENERAL METHOD: Hydroxymethyl (1 mmol) and potassium bromide (1.5 mmol, 0.18 g) were dissolved in ethanol (5 mL) and phosphorus pentoxide (1.5 mmol, 0.23 g) was added. The reaction mixture was stirred at room temperature until the reaction was complete (monitored by TLC or GC). After completion of the reaction, the mixture was filtered and the residue was washed with ethyl acetate (3 x 8 mL). The organic layers were combined, washed with water (10 mL) and dried over anhydrous sodium sulfate. The solvent was removed by concentration under reduced pressure to give the crude 4-cyanobenzyl bromide product. If further purification is required, column chromatography can be used.
