What is the chemical synthesis method of 4-cyano-2,6-diiodophenyl Octanoate?
The chemical synthesis method of 4-cyano-2,6-diiodophenyl octanoate is as follows:
First take 2,6-diiodophenol as the starting material, add an appropriate amount of organic solvent in the reaction vessel, such as dichloromethane, N, N-dimethylformamide (DMF), etc., so that 2,6-diiodophenol is fully dissolved to form a uniform solution.
Then, slowly add an acid binding agent, such as triethylamine, potassium carbonate, etc. The function of the acid binding agent is to neutralize the acid generated during the reaction and promote the reaction to proceed in a positive direction.
Next, add the octanoic acid chloride dropwise to the above mixture. The octanoic acid chloride will acylate with 2,6-diiodophenol to form the precursor of 4-cyano-2,6-diiodophenyl octanoate. This reaction needs to be carried out at an appropriate temperature, generally between 0 ° C and room temperature. Continuous stirring is required during the reaction to ensure that the reactants are in full contact and the reaction can proceed smoothly.
After the acylation reaction is completed, the reaction solution may contain unreacted raw materials, salts formed by acid binding agents, and target products. At this time, the method of extraction can be used to extract the reaction solution with a suitable organic solvent, such as ethyl acetate, ether, etc., so that the target product is transferred to the organic phase.
The organic phase obtained by extraction is washed with water and saturated saline successively to remove residual impurities in the organic phase. After washing, the organic phase is dried with anhydrous sodium sulfate or anhydrous magnesium sulfate to remove moisture.
Finally, the organic solvent in the organic phase is removed by means of reduced pressure distillation, and then the crude product is obtained. The crude product can be further purified by column chromatography with a suitable eluent, such as a mixed solvent of petroleum ether and ethyl acetate, and finally a pure 4-cyano-2,6-diiodophenyl octanoate can be obtained.
Another synthesis idea is to cyanize 2,6-diiodophenol first, and under suitable reaction conditions, a cyano group is introduced to obtain 4-cyano-2,6-diiodophenol. Afterwards, it is esterified with octanoic acid. Suitable catalysts, such as concentrated sulfuric acid, p-toluenesulfonic acid, etc., can be selected for the reaction process, and the subsequent processing steps are similar to those after the acylation reaction. After extraction, washing, drying, distillation and column chromatography purification, 4-cyano-2,6-diiodophenyl octanoate can also be prepared.
