Abstract

Abstract Until now barely explored stacking effects with rate constant enhancements by up to two orders of magnitudes and total accelerations of about 10 7 are found by introduction of aromatic substituents at the N atoms of ethylenediamine of Cu(II) complexes. Ligands containing more than two nitrogen atoms show as an often overlooked factor a strong dependence of the efficiency towards metal coordination.
