THE TRANSITION METAL CATALYZED REACTION BETWEEN Fe(CO)5 AND GROUP V DONOR LIGANDS. A FACILE, HIGH YIELD SYNTHESIS OF Fe(CO)4PPh3

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.

Phosphine addition to pyruvoyl ligands of iron complexes: Formation of zwitterionic metallalactones

Tertiary phosphines react, at -80 °C, with the pyruvoyl-substituted iron complex (CO)4Fe[C(O)C(O)CH3](CO2CH 3) (1) to give rise to phosphonium-substituted metallalactones fac-(CO)3e[C(O)C(CH3/su

Preparation and characterization by 31P-NMR spectroscopy of mixed disubstituted complexes

The disubstituted complexes , where L and L' are different phosphine ligands have been prepared by reaction of the hydrosilyl derivatives with L'.Good results were obtained for L = PMe3 and L' = PPh3, P(OPh)3, P(OEt)3 or P(O-i-Pr)3 but with L' = PMe2Ph, PMePh2, PEt3, a mixture of homo and mixed disubstituted derivatives were obtained.The results can be interpreted in terms of exchange of the L ligand in 3 with L'.The variations in the 31P NMR chemical shifts and 2JPP coupling constants are discussed in the light of the properties of the ligands, and good correlations are revealed with the cone angle and the pKa, respectively.

Low temperature photochemistry of . Stabilization of an intermediate photoproduct in a decomposition reaction

The complex (I), a photoproduct from , is itself photolabile.The UV, IR, resonance Raman spectra of I are described and used for the interpretation of its photochemical behaviour.Irradiation of I in its low-energy MLCT band in the presence of PR3 or a N-donor ligand (L) causes photosubstitution of the last CO ligand of the Fe(1)-bipy moiety, giving the thermally unstable complex (II).Because of this thermal lability of the primary photoproduct, the photochemical reactions were performed in 2-Me-THF at 133 K.The complexes II with L=PR3 decomposed thermally above 200 K, but when L was an N-donor ligand, partial decomposition took place at 133 K.The nature of these decomposition products depend on L.It is suggested that the photochemical reactions occur from a reactive 3LF state after intersystem crossing from the 1MLCT state.Evidence for a close lying 1LF state comes from the resonance Raman spectrum upon 458 nm excitation, which shows anti-resonance Raman effects for all the vibrations.

Infrared, (57)Fe Moessbauer, and (31)P NMR Spectroscopic Characterization of Fe(CO)4L (L = Phosphine and Phosphite)

A series of trigonal bipyramidal Fe(CO)4L complexes has been prepared and characterized by infrared, (57)Fe Moessbauer and (31)P NMR spectroscopy.A linear correlation, with a negative slope, between the CO stretching frequencies and the isomer shifts demonstrates that the triple bond nature of the carbonyl ligands is strengthened with increasing iron-to-phosphorus back donation.The linear dependence of the quadrupole splittings on the isomer shifts with a positive slope has revealed that the ?-donor capability of the phosphine or phosphite ligand is offset by the ?-acceptor capability.The formation of Fe(CO)4L complexes from the corresponding free ligands is accompanied by a downfield shift of (31)P NMR chemical shifts.The coordination shifts are linearly correlated with the Moessbauer isomer shifts. - Phosphinetetracarbonyliron, Phosphitetetracarbonyliron, IR Spectra, (31)P NMR Spectra, (57)Fe Moessbauer Spectra
