Abstract

knowledge on the structural and electronic properties of the relevant reaction intermediates requires the use of innovative and complementary spectroscopic probes. Herein, we combine X-ray Absorption Spectroscopy (XAS) and 1H-NMR to investigate the exchange reaction between two prototypical Cu coordination complexes in solution. By means of multivariate and theoretical analyses, we identify the number, nature and concentration time evolution of the relevant reaction intermediates and quantitatively determine their structures. The XAS and NMR techniques are proven to be complementary experimental tools to track the fate of both the metal and organic portions of reactive systems involving transition metals. The employed combined experimental and theoretical method may be useful in the study of reactive systems involving intermediates that may be labile or silent to conventional detection.
