The (benzylideneacetone) carbonylphosphine iron(0) complexes, Fe(CO)2L(bda), Fe(CO)L2'(bda) and Fe(CO)(dpe)(bda) (L = PEt3, PPhMe2, PPh2Me; L' = PPhMe2, PPh2Me; dpe = 2) have been prepared by irradiating the corresponding tetracarbonylmonophosphine iron(0), tricarbonyldiphosphine iron(0) or tricarbonyl-1,2-bis(diphenylphosphine)ethane iron(0) complexes in benzene in the presence of benzylideneacetone.The X-ray crystal structures of the complexes with L = PEt3 (A) and PPhMe2 (B) have been determined, and show that the Fe atom adopts a distorted octahedral coordinated geometry in which three of the sites are occupied by the bda ligand.The bond parameters in the bda ligand suggest that this coordinated group is intermediate between its ground and first excited states.The complex Fe(CO)2(PEt3)(bda) crystallises in the monoclinic space group P21/c with a 10.203(3), b 12.964(4), c 16.960(6) Angstroem, β 120.00(2) deg, and Z = 4.The structure was solved by a combination of Patterson and Fourier difference techniques and refined by blocked full matrix least squares to R = 0.035 for 3351 unique observed diffractometer data.The complex Fe(CO)2(PPhMe2)(bda) also crystallises in space group P21/c, with a 8.134(3), b 21.394(8), c 11.658(5) Angstroem, β 108.12(2) deg and Z = 4.The structure was solved and refined as above to R = 0.036 for 3498 diffractometer data.The IR and 1H NMR data for all the complexes studied agree with the observed structures.

Reaction of phosphine sulfides LS with Fe(CO)5 at ca. 130-150 deg C gives directly the phosphine complexes LFe(CO)4, which in methanol react with CuCl2 to yield the corresponding chloro complexes L2Fe(CO)2Cl2 in most cases, the chloro complexes

The reaction of Fe(CO)5 and L (L=Group V donor ligand), in the presence of CoCl2 * 2 H2O or CoI2 * 4 H2O as catalyst, results in the synthesis of Fe(CO)4L in good yield.Unusual reactivity patterns for the substitution of CO on Fe(CO)5 by L have been found; for CoI2 as catalyst the reaction rate increases in the order PPh3 ca.AsPh3 ca.P(OPh)3 > SbPh3 > PPh2Me > PPhMe2 > P(C6H11)3 > P(OEt)3 > P(n-Bu)3 > P(OMe)3.These results are interpreted in terms of the variation of the catalyst through interaction of CoX2 with L.
