With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1271-55-2,Acetylferrocene,as a common compound, the synthetic route is as follows.

To a solution of 172 mg KOH (3.07 mmol) in 10 cm3 of EtOH/H2O (1:1) at r.t., 1 g of acetylferrocene(4.38 mmol) was added, followed by dropwise addition of 0.45 cm3 benzaldehyde (4.38 mmol). The thus prepared darkviolet solution was stirred at r.t. for 3 days. Then the reaction mixture was extracted with CH2Cl2(3 ¡Á 10 cm3). The collected organic layers were dried over Na2SO4 and filtered,and the resulting solution was evaporated under reduced pressure to afford the crude product. Isolated enone 9 was characterized and used in the subsequent reaction without further purification.

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

As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO379,mainly used in chemical industry, its synthesis route is as follows.,1271-55-2

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.

With the synthetic route has been constantly updated, we look forward to future research findings about Acetylferrocene,belong iron-catalyst compound

As a common heterocyclic compound, it belongs to iron-catalyst compound, name is Acetylferrocene, and cas is 1271-55-2, its synthesis route is as follows.,1271-55-2

General procedure: The substituted ketone (3 mmol) and KOH(0.2 g) were dissolved in ethanol (5 mL) in a round bottomedflask and stirred at room temperature (25 C) for 10 min. Anethanolic solution of the substituted aromatic aldehyde (3 mmol,5 mL) was added drop wise and the mixture was stirred at roomtemperature. The progress of the reaction was monitored by TLCon silica gel sheets. The reaction was stopped by neutralizingthe stirred solution with 2 M HCl. In most of the cases the productwas obtained as a dark red precipitate after neutralization. It wasthen removed by filtration, washed with water. In the absence ofa precipitate on neutralization, the solution was extracted withethyl acetate (20 mL ¡Á 3). The organic layer was dried overanhydrous sodium sulphate and removed by evaporation underreduced pressure to give a liquid residue. The latter was passedthrough a column of silica gel (230-400 mesh) and eluted withTHF-hexane (1:4) to yield pure compound. All the synthesizedcompounds were well characterized by spectroscopic methodssuch as IR, NMR, Mass and elemental analysis and their spectralcharacteristics were found to be in good general agreement withthose found in literature30.
