Recently we reported an electron spin resonance study of a series of iron carbonyl radical anions Fe/sub n/(CO)/sub m//sup -/.(n = 2-4), which are formed in the reduction of Fe/sub n/(CO)/sub 5/ by alkali metals as well as in the chemical one-electron oxidation of iron carbonylate dianions in tetrahydrofuran. Despite considerable effort, we failed to observe the ESR spectrum of the simplest member of this family, the 17-electron Fe(CO)/sub 4/-.radical anion, although many observations strongly implicated its involvement as a short-lived reaction intermediate. We now find that the closely related (..pi..-olefin)-Fe(CO)/sub 3/-.radical anions are sufficiently stable, for certain olefins, to be studied by electron spin resonance.
