The previously claimed (1) catalysis of the electroreduction of acrylonitrile by means of a complex of Co (I) and 2,2'-bipyridine is shown to be erroneous. The “catalytic currents” result instead from the two-electron reduction of a mixed complex of Co (I) acrylonitrile and 2,2'-bipyridine. The equilibrium and forward rate constants for the formation of the mixed complex have been estimated and its spectrum is given. The behavior of a number of other vinyl monomers, which mimic acrylonitrile, is described.
