3 - iodo - 1 - (trifluoromethoxy) benzene is 3 - iodo - 1 - (trifluoromethoxy) benzene, which is synthesized as follows:
First, it can be prepared from 1 - (trifluoromethoxy) benzene by iodization reaction. In a suitable reaction vessel, use 1 - (trifluoromethoxy) benzene as the substrate, and select a suitable iodizing agent, such as iodine elemental ($I_ {2} $) with a suitable oxidizing agent. Commonly used oxidants such as concentrated sulfuric acid and potassium nitrate are combined. Concentrated sulfuric acid provides an acidic environment. Potassium nitrate generates nitric acid under acidic conditions. Nitric acid can oxidize iodine ions into iodine elemental substances and participate in the iodization reaction. During the reaction, control the temperature, the proportion of reactants and other conditions. Generally, the reaction starts at a low temperature, and gradually heats up to a suitable temperature to make the reaction proceed smoothly. The reaction process is monitored. The reaction endpoint is judged by thin-layer chromatography (TLC). When the raw material point basically disappears, the reaction is completed, and the product is obtained after post-treatment, such as extraction, washing, drying, column chromatography
Second, with 3-iodobenzoic acid as the starting material, the carboxyl group is first converted into a suitable leaving group, such as conversion to acid chloride, and 3-iodobenzoyl chloride can be obtained by treating 3-iodobenzoic acid with dichlorothionyl chloride. After that, it reacts with trifluoromethanol in the presence of a base, which can be selected from triethylamine, etc. Under the action of acid binding agent, 3-iodo- 1 - (trifluoromethoxy) benzoate is generated, and then through reduction reaction, such as reduction with lithium aluminum hydride ($LiAlH_ {4} $), the ester group is reduced to a methyl group, and the target product is 3-iodo- 1 - (trifluoromethoxy) benzene. After each step of the reaction, the corresponding separation and purification operation is required to ensure the purity of the product, so as to facilitate the next step of the reaction.
Third, through the nucleophilic substitution reaction of halogenated aromatics. Select a suitable nucleophilic reagent containing trifluoromethoxy, such as trifluoromethoxy negative ion source (can be prepared by the reaction of trifluoromethanol with a strong base such as sodium hydride), and react with 3-iodohalobenzene (such as 3-iodochlorobenzene or 3-iodobromobenzene) in a suitable solvent (such as N, N-dimethylformamide (DMF)). Pay attention to the anhydrous and oxygen-free environment in the reaction, and avoid the reaction of nucleophilic reagents with impur Control the reaction temperature and time, after the reaction, separation and purification, distillation, recrystallization and other means to obtain pure 3-iodine-1 - (trifluoromethoxy) benzene.
