| 11. | For example, in ferrocene, iron ( II ), ferrous iron is present.
|
| 12. | The half-life for ferrocene liberation is 19.6 hours at 112 �C.
|
| 13. | These data clearly indicate the stability of neutral ferrocene and the cobaltocenium and rhodocenium cations.
|
| 14. | It consists of ferrocene substituted by an acetyl group on one of the cyclopentadienyl rings.
|
| 15. | Direct transmetalation can also be used to prepare ferrocene from other metallocenes, such as manganocene:
|
| 16. | The structure is similar to ferrocene.
|
| 17. | Consequently, the Co C distances are slightly longer than the Fe C bonds in ferrocene.
|
| 18. | The greater size of Hf may diminish HfCl 4's tendency to complex to ferrocene.
|
| 19. | Ferrocene is often used as an internal standard for calibrating redox potentials in non-aqueous electrochemistry.
|
| 20. | For example, ferrocene is alkylated with allyldimethylchlorosilane more efficiently using hafnium chloride relative to aluminium trichloride.
