4-Bromobenzonitrile Chemical Properties,Usage,Production
Chemical Properties
4-Bromobenzonitrile is white to light yellow powder or flakes
Uses
4- Bromobenzonitrile is classified as organic nitriles, which are commonly use solvents and are reacted further for various applications such as manufacture of polymers and intermediates for pharmaceu ticals and other organic chemicals,
Uses
4-Bromobenzonitrile is used as reagents and solvents. Reaction of 2-propanol, 4-bromobenzonitrile, and NaH in the presence of 1.5 mol % Pd2(dba)3 and 3 mol % (S)-(-)2,2?-bis(di-p-tolylphosphino)- 1,1?-binaphthyl at 50°C afforded 4-isopropoxy- benzonitrile in 80% isolated yield. The synthesis of 4-cyanobiphenyl at room temperature in a flow injection microreactor, using a supported catalyst, without the addition of a base gave a product yield of 67±7% (n=6). This was achieved by injecting 4-bromobenzonitrile. The 3-arylation of 2,5-dimethylthiophene with 4-bromopropiophenone, 4-trifluoromethylbromobenzene or 4-bromobenzonitrile gave 3-5 in only 38-50% yields in Palladium-catalysed direct 3-or 4-arylation of thiophene derivatives using aryl bromides.

Tetrahedron Letters, 27, p. 1925, 1986 DOI: 10.1016/S0040-4039(00)84413-5
Synthesis
To a 10 mL glass tube aryl halide (1 mmol), K4FeCN6 (0.6 mmol,220 mg), K2CO3 (1.5 mmol, 207 mg), catalyst (10 mg), and 2 mL DMF were added and the mixture was stirred for appropriate reaction time at 120 ℃ under argon atmosphere. The progress of the reaction was monitored by GC analysis. After completion of the reaction, the reaction mixture was washed with 5 mL water, and the crude product was isolated using dichloromethane (5× 1 mL). Organic extracts were combined, evaporated, and purified by flash chromatography using hexane/EtOAc to give 4-Bromobenzonitrile.
