1958-93-6 - Reference Information
| use | 2-fluoro-6-nitrobenzyl bromide is a new broad-spectrum fungicide pyraclostrobin, which can be used as an intermediate for laboratory research and development and chemical and pharmaceutical synthesis. |
| preparation | add 1/3 kettle capacity carbon tetrachloride solvent, measured azobisisobutyronitrile and 48% hydrogen bromide to the reaction kettle, stir and heat with steam; Heating to about 75 ℃, adding metered o-nitrotoluene and 30% hydrogen peroxide at the same time to keep the temperature unchanged and maintain the reflux state, the dripping time is about 3-4 hours; after the dripping is over, continue to heat preservation and reflux reaction for 1-2 hours, turn off the steam, cool the temperature to normal temperature, and sample and analyze the content of o-nitrobenzyl bromide: liquid separation, the organic layer adopts 20% NaHSO3 After washing three times of aqueous solution and water, it is distilled at normal pressure to remove the carbon tetrachloride solvent; the reaction liquid is recrystallized with petroleum ether, the crystals are centrifuged, and the crystals are rinsed with cold petroleum ether, white o-nitro benzyl bromide solid products. |
