What is A Bis(μ‐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 about?

Aliphatic CÀH bond functionalization by various metalactive oxygen species M m /O n such as superoxo, peroxo, highvalent oxo-metal complexes, etc. is of great importance for understanding the reaction mechanisms of metalloenzymes and utilizing metal complexes as oxidation catalysts. [1][2][3][4] In some cases, aliphatic C À H bond functionalization starts from hydrogen abstraction, and the resulting alkyl radicals undergo a variety of subsequent reactions. [5][6][7] For example, a bis(malkylperoxo)dicopper(ii) complex was suggested as an intermediate in the reaction of a copper(i) complex, [Cu(iPr 3tacn)] + , [8] with O 2 in the presence of 2,4-tert-butylphenol. [5] Very recently, an alkylperoxopalladium(ii) complex was also reported which was produced from the reaction of a hydroperoxopalladium(ii) complex in the presence of a copper(ii) complex as a catalyst. [6] Although various transition-metalalkylperoxo complexes are known, [9] the alkylperoxo complexes generated as reaction intermediates are limited. Previously, we found that the reaction of [Ni 2 (OH) 2+ , and a bis(m-superoxo)dinickel(ii) complex, [Ni 2 (O 2 ) 2 (Me 3 -tpa) 2 ] 2+ . [10] The decomposition of [Ni 2 (O) 2 (M
