Abstract
Paramagnetic anions of dicyanomethylene‐2,2,4,4‐tetramethylcyclobutanone (I) and bis‐(dicyanomethylene)‐2,2,4,4‐tetramethylcyclobutane (II) were produced by electrolytic and chemical reduction. The ESR spectrum of II— indicates fast electron transfer between the two dicyanomethylene groups. 1,3‐π‐interaction and hyperconjugation are considered to be the predominant means of effecting the electron transfer.
