We present a strategy for predicting the unusual 1H and 13C shifts in NMR spectra of paramagnetic bisoximato copper(II) complexes using DFT. We demonstrate good agreement with experimental measurements, although 1H–13C correlation spectra show that a combined experimental and theoretical approach remains necessary for full assignment.

New extractants for Cu2+ ions in raw ore powders or waste water (fluid) were successfully synthesized recently in good yields. Their structures and purity were confirmed by 1H NMR and IR.

We herein present a metal-free, electrosynthetic method that enables the direct dehydrogenative coupling reactions of phenols carrying electron-withdrawing groups for the first time. The reactions are easy to conduct and scalable, as they are carried out in undivided cells and obviate the necessity for additional supporting electrolyte. As such, this conversion is efficient, practical, and thereby
