Electrosynthesis of alkyl and aryloxy titanium(III) complexes; electrochemical and spectroscopic characterization

Electrochemical or chemical reduction of mono- or dicyclopentadienyl TiIV complexes gives the corrsponding radical anions which rearrange rapidly in both cases to the corresponding neutral monocyclopentadienyl TiIII complexes; by a combination of electrochemical and e.s.r. techniques, it was possible to understand the mechanism of reduction of these TiIV complexes.
