Pool together: Oxidative addition of the superoxo ligand inherent to the nickel(II) superoxide 1 onto iron(I) precursor complexes 2 a/2 b leads unexpectedly and exclusively to the first NiFe alkoxo hydroxides 3 a (R=Me) and 3 b (R=tBu). The latter result from an unexpected, selective oxygenation of a C[BOND]H bond of one of the isopropyl groups at the β-diketiminato ligand coordinated to nickel.
