Synthesis, structure, and fluxional behavior of κ1-O-enolatoiron(II) complexes derived from 1,3-dicarbonyl compounds

Highly nucleophilic kappa(1)-O-enolatoiron(II) complexes transFcH((OCRCHCOR)-C-1 (2)-kappa O-1)(DEPE)(2) (1a: R-1 = R-2 =Me, 1b: R-1 = R-2 = OMe, 1c: R-1 = Me, R-2 = OMe) are prepared by the reaction of Fe(N-2)(DEPE)(2) with 1,3-dicarbonyl compounds.
