The three-coordinate, 12-valence electron complexes [(MeBDK)FeR] (MeBDK = [HC(C(Me)NAr)2]−, Ar = 2,6-iPr2C6H3, R = CH2Ph, CH2SiMe3) 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.
Graphical abstractThree-coordinate, 12 valence electron iron alkyls [(MeBDK)FeR] (MeBDK = [HC(C(Me)NAr)2]−, Ar = 2,6-iPr2C6H3, R = CH2Ph, CH2SiMe3) are reported, and their reactions with Lewis bases. Perfluoroaryl borane and -borate activators abstract the alkyl groups to give cationic iron species with perfluorinated arylborate counterions. The paramagnetic cations allow the observation of weak interactions with these anions in solution via 19F NMR spectroscopy.Figure optionsDownload full-size imageDownload as PowerPoint slide
