1. Among its organometallic compounds is ferrocene , the first sandwich compound discovered. 2. This compound on boiling under reflux in benzene is converted to ferrocene . 3. Cobaltocene was discovered shortly after ferrocene , the first metallocene. 4. This seen in the ferrocene -related product of the following reaction: 5. Two more modern alternative fuel additives are ferrocene and methylcyclopentadienyl manganese tricarbonyl. 6. Convergent approaches can also be used to make dendrimers with peripheral ferrocene . 7. Ferrocene was found to be unusually Nobel Prize for Chemistry.8. For example, sodium cyclopentadienide reacts with ferrous chloride to yield ferrocene : 9. The following data are presented relative to the ferrocenium / ferrocene redox couple: 10. The ferrocene scaffold has proved to be versatile.
