Redox reactions of copper(II) upon electrospray ionization in the presence of acridine ligands with an amide side chain

Abstract

The complexation of copper(II) to acridine derivatives has been studied by means of electrospray-ionization (ESI) mass spectrometry. Depending on the position of N-benzoylamino substituents in the acridinic heterocycle, the copper atom involved in the complexation process adopts different oxidation states in the resulting cations.
