SYNLETT 2011, No. 1, pp 0001–0005xx.xx.2010 Advanced online publication: 16.12.2010 DOI: 10.1055/s-0030-1259093; Art ID: P00110ST © Georg Thieme Verlag Stuttgart · New York Abstract: Nickel catalysts have been developed for a wide range of C–C bond formation reactions. Reaction mechanisms proposed for these transformations generally involve catalytic intermediates based on mononickel species. T...

Mononuclear nickel(II)-superoxo and nickel(III)-peroxo complexes bearing a common macrocyclic TMC ligand.

Mononuclear metal-dioxygen adducts, such as metal-superoxo and -peroxo species, are generated as key intermediates in the catalytic cycles of dioxygen activation by heme and non-heme metalloenzymes. We have shown recently that the geometric and electronic structure of the Ni-O2 core in [Ni(n-TMC)(O2)]+ (n = 12 and 14) varies depending on the ring size of the supporting TMC ligand. In this study...

Mononuclear and Dinuclear Manganese(II) Complexes from the Use of Methyl(2-pyridyl)ketone Oxime

The reactions of methyl(2-pyridyl)ketone oxime, (py)C(Me)NOH, with manganese(II) sulfate monohydrate have been investigated. The reaction between equimolar quantities of MnSO(4) . H(2)O and (py)C(Me)NOH in H(2)O lead to the dinuclear complex [Mn(2)(SO(4))(2){(py)C(Me)NOH}(4)] . (py)C(Me)NOH, 1 . (py)C(Me)NOH, while employment of NaOMe as base affords the compound [Mn(HCO(2))(2){(py)C(Me)NOH}(2)...
