| 21. | Reductive cleavage is only restricted to a handful of special substrates, such as ferrocene based hydrazones.
|
| 22. | Reversible delithiation / lithiation of [ [ LiFePO4 | ] ] was successfully demonstrated using ferrocene derivatives.
|
| 23. | Ferrocene can be introduced by heating with the hemicarcerand in a large bulky solvent such as tripiperidylphosphine oxide.
|
| 24. | The iron-containing deposits formed from ferrocene can form a conductive coating on the spark plug surfaces.
|
| 25. | Thus, decamethylferrocene is much more easily oxidised than ferrocene and can even be oxidised to the corresponding dication.
|
| 26. | With a molybdenum-ferrocene complex as catalyst, a turnover number of up to 226 could be achieved.
|
| 27. | For non-aqueous work, IUPAC recommends the use of the ferrocene / ferrocenium couple as an internal standard.
|
| 28. | As an example, figure 1 shows a 54-ferrocene dendrimer which was synthesized by a fast convergent approach.
|
| 29. | Ferrocene can be sublimed in air at over 100 �C with no decomposition; metallocenes are generally purified by vacuum sublimation.
|
| 30. | Using planar chiral ferrocene ligands, enantiomeric excesses ( ee ) upward of 95 % have been observed in aryl couplings.
