  Thermal properties and reactions towards nucleophiles of an iron complex displaying an acetyl and a pyruvoyl ligands

  摘要：

  Thermal evolution at 4 degrees C of the structurally characterized cis(CO)(4)Fe[C(O)C(O)CH3][C(O)CH3](1(2)) gives rise to the cis(CO)(4)Fe[C(O)CH(3)b (1(3)) which, probably owing to synthetic problems, has never been described in the literature. By reaction with anionic nucleophiles (Nu(-)), 1(2) affords anionic trifunctionalized metallalactones {(CO)(3)Fe[C(O)CH3][C(O)C(CH3)(Nu)OC7(O);(Fe-C-7)]}(-) (3) formed by addition of the nucleophile reagent on the P carbon of the pyruvoyl moiety followed by the cyclization of this ligand on a terminal carbonyl of the complex. Anions 3 are characterized by H-1 and C-13 NMR and by X-ray diffraction for the complex with Nu = C(H)(CO2C2H5)(2). Complexes 3 are also prepared by reaction of CH3Li with the neutral metallalactones (CO)(4)Fe[C(O)C(CH3)(Nu)OC7(O):Fe-C-7] (2). The results of this study shed light on the reaction of cyclization of a pyruvoyl ligand as they clearly show that the presence of a second ligand (for example CO2R) with a labile OR group is not required to perform the formation of the metallalactone ring and then that the observed reaction has no connection with organic chain-ring transformations.
