화학적 성질

4-Bromobenzonitrile is white to light yellow powder or flakes

용도

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.

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.
