Sterically directed nitronate complexes of 2,6-di-tert-butyl-4-nitrophenoxide with Cu(ii) and Zn(ii) and their H-atom transfer reactivity

Abstract

The bulky 2,6-di-tert-butyl-4-nitrophenolate ligand forms complexes with [Tp^tBuCu^II]⁺ and [Tp^tBuZn^II]⁺ binding via the nitro group in an unusual nitronato-quinone resonance form (Tp^tBu = hydro-tris(3-tert-butyl-pyrazol-1-yl)borate).
