2,4-DICHLOROBROMOBENZENE - Reference Information
| application | 2, 4-dichlorobromobenzene is used to synthesize new sweeteners and some chiral drug intermediates, as well as clinical drugs and chemical raw materials Intermediates. In addition, 2, 4-dichlorobromobenzene is also mainly used in synthetic medicine, pesticides and rubber additives. It is mainly used in the pesticide industry to synthesize the paddy herbicide Gualao Dan. It is a selective non-hormonal thiocarbamate vinegar. Herbicide has great development prospects. |
| preparation | put a 30 mL round bottom flask into ice. 0.2 mL arylhydrazine hydrochloride (0.5 mmol) and cyclopentyl methyl ether (CH2Cl2) were added to the mixture. Gently add 2.4 equivalent of boron bromide to the mixture. Drop 0.2 mL dimethyl sulfoxide into the mixture through a syringe. Place the mixture in a heating plate (80°C). Stir the mixture in air for 1 hour. Liquid extraction with CH2Cl2 to purify the product. Clean the product with saturated NaHCO3. Dry the product on Na2SO4. The product 1-bromo-2, 4-dichlorobenzene (hexane 100%/hexane: EtOAc = 20:1) was purified by column chromatography. |
