摘要:
Factors determining the effect of Zn-II ions on the catalytic activity of the Ni-II complexes with 2,2'-bipyridine (bpy) in the reduction of organobalides were elucidated by cyclic voltammetry and electrolysis. The mechanism proposed involves the reduction of the Ni(II)bpy complex to Ni(0)bpy, the oxidative addition of organohalides to the Ni(0)bpy complex, and nickel transmetallation with the cathode-generated Zn-0 to form an organozinc compound.
