With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1271-51-8,Vinylferrocene,as a common compound, the synthetic route is as follows.

General procedure: Synthesized according to general procedure C using hydrazone (0.0800 g, 0.255 mmol), vinyl-ferrocene (0.0541 g, 0.255 mmol) in trifiuorotoluene (1.28 mL) and heated at 80 C for three hours. Volatiles were removed and the crude product was isolated by column chromatography with 100% CH2CI2, then 50% EtOAc/w-hexanes and gradually increased to 100% EtOAc. The title compound was obtained as dark red crystals (0.1024 g, 0.237 mmol, 93 % isolated yield). TLC Rf = 0.22 in 100 % EtOAc. ?
