High‐Valent Nickel Complexes Supported by a Functionalized PC(sp3)P Pincer Ligand: Properties and Catalysis

Year: 2025

Type: article

Abstract: This article presents the synthesis and characterization of a series of robust high‐valent organometallic nickel (Ni) complexes stabilized by a functionalized PC(sp3)P pincer ligand. Notably, the nickel center, covalently confined within the 3D ligand framework, demonstrates predictable coordination and redox behavior, coupled with remarkable stability across oxidation states +2, +3, and +4. These states were found to interconvert via one‐electron transfer reactions. Among these complexes, the Ni(III)‐PC(sp3)P species was identified as an efficient catalyst for the mild and selective hydrosilylation of alkenes, operating through a nonoxidative reaction mechanism.
