Abstract
Reacting a bidentate ligand H2L, 2-(2-methoxybenzyl)-2-methylpropane-1,3-dithiol, with Fe-3(CO)(12) formed a diiron hexacarbonyl complex (1Me) from which a diiron hexacarbonyl complex (1H) pendant with a phenolic group was derived via in-situ demethylation. Further deprotonation of complex 1H gave a diiron pentacarbonyl species (1) in which a rare bond between the soft metal Fe-I and the relatively hard base phenolate formed, Fe-I-OR (R = phenolic moiety). This bonding may be a suitable mimic of the bonding feature, ((FeFeI)-Fe-I)R-OH/OH2 found in the FeFel-hydrogenase. (C) 2010 Elsevier B.V. All rights reserved.
