With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1271-42-7,Ferrocenecarboxylic acid,as a common compound, the synthetic route is as follows.
In a three-necked flask, 4.6 g (0.02 mmol) of dry ferrocenecarboxylic acid and 80 mL of anhydrous benzene were added.Under nitrogen protection,6.24 g (0.03 mmol) of phosphorus pentachloride was slowly added in several portions, and stirred at room temperature for 3 h.The benzene is distilled off under reduced pressure, and petroleum ether (60-90 C) is extracted to obtain a deep red solution, distilled under reduced pressure, and cooled.Dark red needle crystals are precipitated, yield 80%
1271-42-7, 1271-42-7 Ferrocenecarboxylic acid 499634, airon-catalyst compound, is more and more widely used in various fields.
