The method of preparing o-iodotrifluorotoluene often follows several paths. One is to start with o-toluidine, which is obtained by diazotization and iodine substitution. First, o-toluidine is reacted with sodium nitrite and hydrochloric acid at low temperature to perform diazotization to obtain o-methyl diazonium salt. This step requires temperature control to prevent the decomposition of diazonium salts. Then, the diazonium salt is reacted with potassium iodide, and the diazonium group is replaced by an iodine atom to obtain o-iodotoluene. Finally, a specific fluorinating agent, such as antimony trifluoride, reacts with o-iodotoluene to convert the methyl group into trifluoromethyl, and then becomes o-iodotrifluorotoluene.
There are also those who use o-chlorotrifluorotoluene as The Grignard reagent is first made from magnesium chips and o-chlorotrifluorotoluene, and then reacts with iodine. The chlorine atom is replaced by the iodine atom, and the final product is o-iodine-trifluorotoluene. In this way, it needs to be operated in an anhydrous and anaerobic environment to avoid the failure of Grignard's reagent.
There are also trifluoromethylbenzene as a starting material and prepared by halogenation reaction. Under specific conditions, an appropriate halogenating agent, such as iodine and an appropriate catalyst, reacts with trifluoromethylbenzene to introduce iodine atoms into the ortho-site of the benzene ring to obtain o-iodine-trifluorotoluene. In this process, the choice of catalyst and the control of reaction conditions have a great impact on the yield and purity of the product.
All methods have advantages and disadvantages. In actual preparation, it is necessary to comprehensively weigh factors such as the availability of raw materials, cost, and difficulty of reaction conditions to determine the appropriate method.
