- Benzyl anion abstraction from a (β-diiminato)Fe(II) benzyl complex
-
The 3-coordinate 12 VE iron(II) benzyl complex [(nacnac)- Fe(CH2Ph)] reacts with B(C6F5)3 to yield a paramagnetic contact ion pair with an η2-(o,m)-[PhCH2B(C6F5) 3] anion, which was characterised by X-ray diffraction.

- Neutral and cationic Fe(II) β-diketiminate complexes

The three-coordinate, 12-valence electron complexes [(MeBDK)FeR] (MeBDK = [HC(C(Me)NAr)2]-, Ar = 2,6-iPr 2C6H3, R = CH2Ph, CH 2SiMe3) are reported as well as their reactivity towards Lewis bases. With perfluoroaryl borane and -borate type activators, the monoalkyls react to give alkyl-free paramagnetic cationic iron species counterbalanced by perfluorinated arylborate anions. The paramagnetic nature of the cations permits the observation of weak and dynamic interactions with these anions via 19F NMR spectroscopy.
