O2 activation at a trispyrazolylborato nickel(ii) malonato complex

Abstract

To support mechanistic inferences made for an iron-based dioxygenase model, a nickel analogue, i.e. a TpNi-malonate (1) was prepared. 1 proved to represent a rare case of a nickel complex reacting with O₂ in a controlled manner – mechanistically different from the iron case – and leads to hydroxylation of the malonate.
