ABSTRACT:

The neutral carbonyl compounds of iron, Fe(CO) sub 5 , Fe sub 2 (CO) sub 9 , Fe sub 3 (CO) sub 12 , and the related carbonylate dianions, Fe(CO) sub 42- , Fe sub 2 (CO) sub 82- , Fe sub 3 (CO) sub 112- , Fe sub 4 (CO) sub 132- , and their conjugate acids, HFe(CO) sub 4- , HFe sub 2 (CO) sub 8- , HFe sub 3 (CO) sub 11- , HFe sub 4 (CO) sub 13- , occupy an important position in organometallic chemistry. Several of these reagents are employed as useful stoichiometric reagents or precursors to catalytically active species. They are all diamagnetic and their very considerable chemistry has been discussed virtually exclusively in terms of even-electron mechanisms. Our studies, however, have revealed a new series of iron carbonyl species which parallels the carbonylate dianions and are related to the latter by having one less electron. The existence of these radical anions, their conjugate protonated species (vide infra), and other organoiron radicals (vide infra) suggests an important but not yet generally recognized role for one-electron pathways in the chemistry of iron carbonyl compounds.
