Copper(I)-dioxygen reactivity in a sterically demanding tripodal tetradentate tren ligand: Formation and reactivity of a mononuclear copper(II) end-on superoxo complex (Conference Paper)

摘要

Reaction of a copper(I) complex supported by a sterically demanding tripodal tetradentate ligand, HIPT _3tren, and O _2 gave a mononuclear copper(II) end-on superoxo complex. Spectroscopic (UV/Vis, resonance Raman, ESR, and ~1H-NMR) and DFT studies have been performed. The O _2-binding process as well as the reaction toward external substrates have been investigated kinetically to demonstrate the unique behavior of the copper(II) end-on superoxo complex, which may occur as a result of the existence of the hydrophobic core around the copper coordination sphere created by the HIPT _3tren ligand.
