ZR BG DE - Reference Information
| application | 4-bromo-2-chloroaniline is a kind of brominated arylamine, which is an important organic synthesis intermediate. it is the main raw material of medicine, pesticide, antihistamines, photographic drugs, etc., and is widely used in chemical reagents, fine chemicals, special materials and other industries. |
| preparation | in a 25mL reaction tube, 2-chloroaniline (25.4mg,0.2mmol), sodium bromide (30.8mg,0.3mmol), sodium bisulfate hydrate (55.2mg,0.4mmol),4-(phenylacetylene) benzonitrile (4.1mg,0.02mmol), water (72mg,4mmol) and acetonitrile (2mL) were stirred for 7 hours under the irradiation of three 2-watt LED lamps. After the reaction was completed, the white solid 4-bromo-2-chloroaniline (34.8mg,85%) was separated by column chromatography. |
