The method of preparing (tricyclohexylphosphine) (1,5-cyclooctadiene) (pyridine) iridium (I) hexafluorophosphate is the key to chemical synthesis. The method requires the preparation of all kinds of raw materials, tricyclohexylphosphine, 1,5-cyclooctadiene, pyridine and iridium-containing salts, and hexafluorophosphoric acid is also indispensable.
In a clean reaction vessel, according to a certain ratio, the iridium salt is first mixed with 1,5-cyclooctadiene. The combination of the two phases needs to be carried out at a suitable temperature and under an inert gas atmosphere. Inert gases, such as nitrogen or argon, can prevent the reactants from being disturbed by external air and cause impure reactions. Temperature control is related to the rate of the reaction and the purity of the product. It often depends on the specific reaction conditions, either at room temperature or heated to a moderate temperature.
When the iridium salt reacts with 1,5-cyclooctadiene for a certain period, tricyclohexylphosphine is added. The addition of tricyclohexylphosphine can change the electron cloud distribution of the compound and affect the progress of the reaction. This step also requires attention to the temperature and time of the reaction to make the reaction sufficient.
Subsequently, pyridine is slowly injected into the reaction system. Pyridine acts as a ligand and combines with the previously formed intermediate product to construct a complex iridium complex structure. In this process, the pH, temperature and stirring rate of the reaction system are all key factors affecting the reaction. Fine regulation is required to make the reaction smooth.
When the above reaction is generally completed, hexafluorophosphoric acid is slowly added. Hexafluorophosphoric acid undergoes an ion exchange reaction with the formed iridium complex, and finally (tricyclohexylphosphine) (1,5-cyclooctadiene) (pyridine) iridium (I) hexafluorophosphate. After the product is formed, it is extracted, separated, and purified by recrystallization with a suitable solvent to obtain a high-purity product. The whole synthesis process requires fine operation and strict adherence to various reaction conditions to obtain ideal results.

There is a question today about the market price of (tricyclohexylphosphine) (1,5-cyclooctadiene) (pyridine) iridium (I) hexafluorophosphate). This is a chemical substance, and its price often varies due to many factors.
One is related to purity. If the purity is extremely high, it is almost flawless, and can be used in high-end scientific research experiments. It requires fine processing to refine, and its price is high. Just like refined jade, it is finely carved and priceless. However, if the purity is slightly lower, it is only suitable for general industrial use, and does not require extreme purification. Its price is cheap, just like ordinary stone. Although it is also useful, the price is not high.
Second, the yield is also the key. If the output of this product is scarce, it is like a treasure in the deep mountains, and it is not easy to find. Because the supply exceeds the demand, the price will remain high. On the contrary, if it is produced in large quantities, such as rice in the plains, the price will tend to be easy.
Third, the state of market demand also affects its price. If at some time the demand for it in the scientific research field is like a thirsty soil looking for rain, and many studies need this product, the merchant will raise the price at the opportunity to make a big profit. If the demand is cold, just like a fan in winter, no one cares, and the merchant has to reduce the price in order to sell it.
As far as I know, the price of this product in the market may be between hundreds and thousands of yuan per gram. However, this is only a rough estimate. The actual price should be based on the real-time market situation, and the changes in supplier quotations and market supply and demand can be obtained in order to obtain an accurate price.
