Acetylferrocene was synthesizedaccording to previously reported procedures [49]. Briefly, 85% phosphoric acid (4?mL) was slowly added to a stirred solution of ferrocene (4.0?g, 21.5?mmol) and acetic anhydride (13.3?mL, 140.0?mmol). The mixture was heated in a water bath maintained at 50?C for 10?min and then cooled in ice. Water (25?mL) was added to the mixture, that was then neutralized with NaHCO3 until the end of CO2 formation. CH2Cl2 (50?mL) was added and the orange organic layer was separated and retained in the dark, whereas the brown-coloured aqueous layer washed with a further 20?mL of CH2Cl2. The combined organic fractions were washed twice with water and then dried with anhydrous magnesium sulfate. Crude acetyl ferrocene, obtained removing the solvent under reduced pressure, was purified by silica gel column chromatography using a 95/5 mixture of petroleum ether/ethyl acetate as starting eluent to first separate the unreacted ferrocene. Once the ferrocene was eluted, the eluent was replaced by 100% ethyl acetate to collect acetyl ferrocene, that was then obtained by removing the solvent on a rotary evaporator.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.102-54-5,Ferrocene,as a common compound, the synthetic route is as follows.

General procedure: An oven-dried vial was charged with anisole 1a (0.75 mmol, 1.0 equiv), acetic anhydride 2a (1.5 mmol, 2.0 equiv) and TFA (0.8 mL). The reaction mixture was stirred at room temperature and monitored by TLC or GC-MS. The reaction typically took 1.5 h to complete. Upon completion, aqueous sodium hydrogen carbonate was added and the aqueous phase was extracted with ethyl acetate (3 x 20 mL). The combined organic layers were dried over Na2SO4 and concentrated. The crude product was purified by silica gel column chromatography to afford ketone product 3a. Alternatively, the product can also be obtained without workup: upon completion, the solvent was removed under reduced pressure and the residue was subjected to silica gel flash column chromatography.
