What is the preparation method of Bis (p-tolyl) iodonium Hexafluoroantimonate
The method of preparing bis (p-toluphenyl) iodohexafluoroantimonate is obtained through several steps. The first is to take p-toluphenyl boronic acid and iodobenzene under the catalysis of palladium, with potassium carbonate as a base, in an organic solvent, such as a mixture of dioxane and water. Suzuki-Miyungpo coupling reaction. This step can obtain a di (p-toluphenyl) iodized salt intermediate. During the reaction, the temperature should be controlled in an appropriate range, usually about 80 to 100 degrees Celsius, and the reaction should be fully stirred.
The obtained di (p-toluphenyl) iodized salt intermediate is dissolved in a suitable solvent, such as dichloromethane. Another solution of hexafluoroantimonic acid is prepared, and it is slowly dropped into the solution containing the intermediate. This process should be carried out at a low temperature, such as 0 to 5 degrees Celsius, in a nitrogen-protected atmosphere to prevent the product from being affected by oxidation or other side reactions. After the drop is completed, continue to stir for a while to promote the complete reaction.
After the reaction is completed, separate the product in an appropriate manner. An appropriate amount of bad solvent can be added to precipitate the product, followed by filtration, washing, drying and other steps to obtain pure bis (p-toluene) iodine hexafluoroantimonate. The whole process needs to pay attention to the precise control of the reaction conditions at each step to ensure the yield and purity of the product.
What are the precautions for the use of Bis (p-tolyl) iodonium Hexafluoroantimonate?
Bis (p - tolyl) iodonium Hexafluoroantimonate is a commonly used reagent. When using it, there are several precautions to pay attention to.
