O 2 takes activation lessons : OO bond activation can be achieved depending on the nature of the heterometal M in [LNi(μ,η 2 :η 2 ‐O 2 )M] complexes. The reduction of the nickel(II) superoxide 1 with potassium affords the peroxide 2 , which, upon replacement of the K + ion in 2 by the non‐redox‐active L′Zn + ion, leads to transient 3 , which subsequently abstracts two solvent hydrogen atoms to give the heterobimetallic complex 4 . L, L′=β‐diketiminates.
