Abstract

In the nick(el) of time: Bis(μ-oxo) dinickel(III) complexes 2 (see scheme), generated in the reaction of 1 with H2O2, are capable of hydroxylating the xylyl linker of the supporting ligand to give 3. Kinetic studies reveal that hydroxylation proceeds by electrophilic aromatic substitution. The lower reactivity than the corresponding μ - η2: η2 - peroxo dicopper(II) complexes can be attributed to unfavorable entropy effects.
