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<sup>III</sup> 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<sup>III</sup>Cl<sub>2</sub> <a>species can be regenerated via a reaction with PhICl<sub>2</sub></a>.
