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

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 (NiCl2)-Cl-III species can be regenerated via a reaction with PhICl2.

In this study, a stable Ni-III dichloride complex supported by a tetradentate pyridinophane N-donor ligand was isolated, characterized, and found to undergo efficient photoreductive chlorine elimination upon irradiation in both solution and solid-state. The (NiCl2)-Cl-III species can be regenerated via a reaction with PhICl2.
