摘要：

A radical approach: The reaction of [Ni2(OH)2(Me 2-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(Mel-tpa-COO)]+ and [Ni2(Me1-tpa-CH 2O)2]2+. Me2-tpa=bis[(6-methyl-2- pyridyl)methyl] [(2-pyridyl)methyl]amine.
