A bis(mu-alkylperoxo)dinickel(II) complex as a reaction intermediate for the oxidation of the methyl groups of the Me-2-tpa ligand to carboxylate and alkoxide ligands
A radical approach: The reaction of [Ni2(OH)2(Me2‐tpa)2]2+ with H2O2 resulted in the peroxidation of a methyl group of the Me2‐tpa ligand to produce a bis(μ‐alkylperoxo)dinickel(II) complex (see ORTEP diagram) as a reaction intermediate for further oxidation to carboxylato and alkoxo complexes [Ni(Me1‐tpa‐COO)]+ and [Ni2(Me1‐tpa‐CH2O)2]2+. Me2‐tpa=bis[(6‐methyl‐2‐pyridyl)methyl][(2‐pyridyl)methyl]amine.
