Iron Catalysis in Organic Synthesis: A Critical Assessment of What It Takes To Make This Base Metal a Multitasking Champion

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1273-86-5,Ferrocenemethanol,as a common compound, the synthetic route is as follows.

General procedure: A mixture of aryl alcohol (1 mmol) and [FemDMMerA]Y (100 mg) in solvent(5 mL) was refluxed in oil bath. After completion of the reaction as monitored byTLC, the reaction mixture was filtered to remove insoluble SILP catalyst.Evaporation of solvent in vacuuo followed by column chromatography over silicagel using petroleum ether/ethyl acetate (95:5 v/v) afforded pure aldehydes.

Name is Ferrocenecarboxaldehyde, as a common heterocyclic compound, it belongs to iron-catalyst compound, and cas is 12093-10-6, its synthesis route is as follows.,12093-10-6

General procedure: A solution of pure TsNHNH2 (15 mmol) in methanol (30 mL) was stirred and heated to 60 C until the TsNHNH2 dissolved. The mixture was cooled to room temperature. Then a solution of ferrocenylketone (10 mmol) in methanol was dropped into the mixture slowly. After approximately 0.5-2 h, the crude products could be obtained as solid precipitate. The precipitate was washed with petroleum ether then removed in vacuo to give the pure products. In general, the yields were 68-86 %. Because of the relatively low activity of some ketones, their reactions at room temperature may be incomplete. They should be reacted in refluxing methanol. The reaction could be monitored by TLC.
