What is the synthesis method of 1-trifluoromethyl-1,2-benziodoxol-3 (1h) -one?
1-Trifluoromethyl-1,2-benzoiodoxacyclopentyl-3 (1H) -one, often referred to as Togni reagent, is synthesized as follows:
To prepare this reagent, first take o-iodobenzoic acid and dissolve it in a suitable organic solvent, such as dichloromethane. Then, slowly add an appropriate amount of trifluoromethylation reagent to this solution, such as trifluoromethylsulfonyl fluoride or trifluoromethylated silicon reagent. This reaction needs to be carried out at a specific temperature and under the protection of an inert gas, such as in a low temperature and nitrogen atmosphere. During the reaction, constant stirring is required to ensure that the reactants are fully contacted and the reaction occurs smoothly.
The carboxyl group of o-iodobenzoic acid reacts chemically with the trifluoromethylation reagent. After a series of complex chemical transformations, the carboxyl group is gradually converted into a part of the target structure, and trifluoromethyl is introduced at the same time. During this process, the reaction process should be closely monitored, and the degree of reaction can be tracked by means of thin-layer chromatography.
When the reaction reaches the desired degree, the reaction mixture is post-treated. First, the organic phase containing the target product is extracted with an appropriate solvent. After that, the organic phase is dried to remove the moisture. Desiccants such as anhydrous sodium sulfate can be used. Finally, 1-trifluoromethyl-1,2-benzoiodoxacyclopentyl-3 (1H) -one with high purity can be obtained by means of reduced pressure distillation or column chromatography. The whole synthesis process requires fine operation and strict control of reaction conditions to obtain satisfactory yield and purity.

Therefore, it needs to be stored in a dry and well-ventilated place, away from water sources and moisture to prevent moisture from dissolving.
Furthermore, temperature control is also crucial. High temperature environments should be avoided, which may reduce the stability of the compound and even cause decomposition reactions. It should be stored in a low temperature environment. Generally speaking, the suitable temperature range is between 2 and 8 degrees Celsius, so as to maintain the stability of its chemical structure and properties.
In addition, when storing the substance, it is also necessary to ensure that it is isolated from other chemical substances. Because of its certain chemical activity, if it comes into contact with incompatible substances or undergoes chemical reactions, it will lead to dangerous conditions. Like strong oxidizing agents, reducing agents, etc., should be stored separately.
During transportation, the packaging must be stable and tight. Suitable packaging materials should be used to ensure that it will not be damaged and leaked due to vibration or collision during transportation. The packaging material should have good compression and shock resistance to prevent the leakage of compounds caused by package damage, which will cause harm to the environment and personnel.
At the same time, the temperature and humidity during transportation also need to be strictly controlled. Transportation equipment with temperature adjustment function can be used to maintain a suitable temperature range. And moisture-proof measures should be taken, such as the use of moisture-proof packaging materials or the placement of desiccant in the package.
In addition, transportation personnel must be familiar with the characteristics of the compound and emergency treatment methods. In the event of an unexpected situation such as a leak during transportation, they can quickly and correctly take countermeasures to reduce the harm. For example, if a leak occurs, the scene should be isolated immediately, personnel should be evacuated, and appropriate methods should be selected for cleaning and disposal according to its chemical properties.
