To prepare 4- (bromomethyl) -1 -fluoro-2 -nitrobenzene, it is often obtained by bromomethylation starting with o-fluoronitrobenzene.
First take an appropriate amount of o-fluoronitrobenzene, place it in a round bottom flask, use carbon tetrachloride as a solvent, and add an initiator such as benzoyl peroxide. Heat up to a suitable temperature to make the system reach the reaction conditions. Slowly add a mixture of polyformaldehyde and hydrogen bromide. The mixture needs to be prepared in advance and the proportion is guaranteed to be appropriate. After adding it dropwise, continue to stir the reaction for several hours to make the reaction sufficient. The reaction principle of this step is to use paraformaldehyde to generate bromomethyl positive ions under the action of hydrogen bromide, which attack the o-fluoronitrobenzene ring and replace it
After the reaction is completed, pour the reaction solution into the separation funnel, wash with an appropriate amount of dilute alkali solution to remove unreacted acids and impurities. Separate the organic phase, dry it with anhydrous magnesium sulfate, filter out the desiccant, and then distill under reduced pressure to recover the solvent and initially separate the product.
The crude product is purified by column chromatography, and silica gel is used as the stationary phase. Petroleum ether and ethyl acetate are prepared into a mobile phase in a certain proportion. The fraction containing the target product is collected, and then the residual solvent is removed by vacuum distillation to obtain pure 4- (bromomethyl) -1 -fluoro-2 -nitrobenzene. During operation, pay attention to factors such as temperature, drip rate, and material ratio to prevent side reactions and improve the yield and purity of the product.

4 - (bromomethyl) -1 -fluoro-2 -nitrobenzene is an organic compound. When storing and transporting it, the following numbers should be paid attention to:
First, the storage environment. This compound is sensitive to heat and light. It should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and close to heat sources to prevent it from being decomposed by heat or causing other chemical reactions.
