Photoreductive chlorine elimination from a Ni(iii)Cl2 complex supported by a tetradentate pyridinophane ligand

Abstract

Herein we report the isolation, characterization, and photoreactivity of a stable Ni^III dichloride complex supported by a tetradentate pyridinophane N-donor ligand. Upon irradiation, this complex undergoes an efficient photoreductive chlorine elimination reaction, both in solution and the solid-state. Subsequently, the Ni^IIICl₂ species can be regenerated via a reaction with PhICl₂.
