The research aimed to investigate the reactivity of nickel(0) complexes coordinated with 2,2'-bipyridine (bpy) in the electrochemical reduction of organic halides. The study focused on understanding the mechanism of the catalytic process and identifying the intermediates formed during the reduction. The researchers used nickel complexes with varying numbers of bpy ligands and different organic halides, including alkyl and aryl halides such as propyl iodide, amyl iodide, phenyl bromide, and mesityl bromide. The experiments involved electrochemical techniques like cyclic voltammetry and preparative electrolysis. The study concluded that nickel(0) complexes with fewer bpy ligands were more reactive in the oxidative addition to organic halides, leading to the formation of σ-organonickel intermediates.
