Özet
The coordination chemistries of several 2,5-bis(phosphine)-1,4-hydroquinones, (2,5-bis(PiPr2)-3,6-difluoro-1,4-hydroquinone (1a), 2,5-bis(PiPr2)-1,4-hydroquinone (1b), (2,5-bis(PPh2)-3,6-difluoro-1,4-hydroquinone (1c), and 2,5-bis(PPh2)-1,4-hydroquinone (1d)) were investigated. Reactions of these ligands 1a–d with excess (∼2.5) of bis(cyclopentadienide)nickel, and in case of 1a, with bis(pentamethylcyclopentadienide)nickel, resulted in the formation of bimetallic nickel complexes 2a–d and 3a, where both [P,O] chelating pockets of the ligands were occupied by CpNi or Cp∗Ni moieties, respectively. Cyclic voltammetric (CV) scans on complexes 2a–d contained a common feature of two reversible/quasi-reversible waves and one irreversible redox event. Complex [2a][PF6] was isolated by the oxidation of 2a with ferrocenium hexafluorophosphate. Spectroscopic, structural, and synthetic studies were carried out …
