Electrochemical Model Processes for Reductive Cleavage of the Cobalt-Carbon Bond

  • Chapter

Part of the book series: Experientia Supplementum ((EXS,volume 18))

Summary

Cobalt complexes with a tetradentate equatorial chelating agent (chel) an organic group (R) and a donor solvent molecule (S) in the axial positions of a pseudo-octahedral structure [RCoIII(chel)S]+,0, undergo reversible one-electron transfers at the D.M.E. in dimethylformamide, yielding organometallic anions by a one-step or two-step reduction when (chel) is a dianion or monoanion respectively. Stability of organometallic anions and mechanism of cleavage of the Co-C bond depend on the nature of R and of (chel). Cleavage yielding carbanions is proposed as model mechanism for the transfer of organic groups from alkylcobalamines.
