Csingle bondO bond activation and subsequent decarbonylation of ester promoted by Fe(PMe3)4

The reactions of 8-quinolinyl esters with iron(0) complex supported by trimethylphosphine ligands afforded four hexa-coordinate chelate-[C,N] iron(II) carbonyl complexes 5–8 via Cacylsingle bondO bond activation and subsequent decarbonylation. Complexes 5–8 were characterized through IR, 1H NMR, 31P NMR and elemental analysis. The crystal structures of complexes 5–8 were determined by X-ray diffraction.
