Electron transfer within β-diketiminato nickel bromide and cobaltocene redox couples activating CO2

Zimmermann, Philipp; Kilpatrick, Alexander ; Ar, Deniz; Demeshko, Serhiy; Cula, Beatrice; Limberg, Christian

Reduction of β-diketiminato nickel(II) complexes (LtBuNiII) to the corresponding nickel(I) compounds does not require alkali metal compounds but can also be performed with the milder cobaltocenes. LtBuNiBr and Cp2Co have ...

High-spin square planar iron(II) alkali metal siloxide complexes – influence of the alkali metal and reactivity towards O2 and NO

Beckmann, Fabian; Kass, Dustin; Keck, Matthias; Yelin, Stefan; Hoof, Santina; Cula, Beatrice; Herwig, Christian; Krause, Konstantin; Ar, Deniz; Limberg, Christian

Complexes [L2Fe][Li(DME)]2, 1(DME), {[L2Fe][Na2(DME)3]}∞, 2(DME) and [L2Fe][K(DME)2]2, 3(DME) were synthesized by deprotonation of LH2 (LH2=O(SiPh2OH)2) with the respective alkali metal tert-butoxides followed by ...

Selective Transformation of Nickel-Bound Formate to CO or C−C Coupling Products Triggered by Deprotonation and Steered by Alkali-Metal Ions

Zimmermann, Philipp; Ar, Deniz; Rößler, Marie; Holze, Patrick; Cula, Beatrice; Herwig, Christian; Limberg, Christian

A deceptively simple proton abstraction from nickel-bound formate not only prepares the resulting CO22− unit for the release of CO in contact with electrophiles but opens up unique complex reaction schemes including reduction ...
