| Abstract: | A study has been made of the influence of Co(II) and Ni(II) ions on the kinetics of the homogeneous reduction of gem-dichlorocyclopropanes by anthracene anion radicals. It has been shown that Co(II) and Ni(II) ions accelerate this process. The observed effect depends on the nature and concentration of the metal ion and also on the type of gem-dichlorocyclopropane. Two mechanisms are examined: 1) homogeneous reduction of metal ions by anthracene anion radicals with the formation of univalent and zero-valent metals that are more effective reducting agents; and 2) activation of a dichlorocyclopropane molecule by previous coordination with a metal ion.A.
