Uebergangsmetall-Silyl-Komplexe. XL. Umsetzung von cis-Fe(CO)4(SiCl3-nMen)2 (n = 1-3) mit Phosphinene: Konkurrenz von CO-Substitution, SiR3-Abspaltung und Bildung zweikerniger, SiR2-verbrueckter Komplexe

Upon reaction of benzene solutions of the bissilyl complexes cis-Fe(CO)4(SiCl3-nMen)2 (n = 1-3) with triphenylphosphine no disilane elimination takes places.Instead, formation of phosphine-substituted bissilyl or hydrido silyl complexes, disiloxanes and F

Carbon-carbon bond formation at a diiron center. 5. Versatile action of phosphines on Fe2(CO)6(μ-COEt)(μ-CRCR′H) complexes (R = R′ = Ph, H)

The reaction of Fe2(CO)6(μ-COEt) (μ-CRCR′H) complexes (R = R′ = Ph, H) with the phosphines PPh3 and PMe2Ph is dependent on both phosphine and R. In the case where R = R′ = Ph, reaction with PPh3 leads only to the formation of Fe(CO)3(PPh3)2 in boiling hexane. With PMe2Ph the reaction occurs with CO substitution to give Fe2(CO)5(PMe2Ph)(μ-CPhCPhC(OEt)H) (3), in which the organic fragment is η1:η3 bound through the carbons to the two iron atoms and η1(O) bound through oxygen of the ethoxy group to an iron atom. In the case where R = R′ = H, reaction with PMe2Ph leads to the formation of Fe-(CO)5-n(PMe2Ph)n (n = 1, 2) in boiling hexane. With PPh3, coupling of the two organic bridges is observed and the reaction occurs without CO loss, leading to Fe2(CO)6(PPh3)(μ-C(OEt)CHCH2) (5). Protonation of 5 with HBF4·Et2O gives [Fe2(CO)7(PPh3)(μ-C(OEt)CH(Me))][BF 4], the structure of which has been established by an X-ray structure determination: triclinic; space group P1; a = 12.305 (1) A?, b = 16.069 (2) A?, c = 8.210 (1) A?; α = 95.61 (1)°, β = 90.35 (1)°, γ = 87.10 (1)°; Z = 2. The structure was solved and refined to R and Rw values of 0.031 and 0.032, respectively, with use of 3226 reflections.

Tricarbonyl(phosphine)ferrates(2-), Fe(CO)3(PR3)2-, and their derivatives

A two-step synthesis of K2[Fe(CO)3(PR3)] (PR3 = PPh3, PMe2Ph, and PMe3) from the corresponding Fe(CO)4(PR3) has been developed. Treatment of Fe(CO)4(PR3) with a methanolic solution of [Et4N]OH provided the corresponding monohydrides HFe(CO)3(PR3)-. Deprotonation of monohydrides by K[sec-Bu3BH] in refluxing tetrahydrofuran gave 50-70% isolated yields (based on Fe(CO)4(PR3)) of the thermally stable but exceedingly air-sensitive salts K2[Fe(CO)3(PR3)], which were characterized by elemental analysis, infrared spectra, and reactivity patterns. These are the first isolated salts containing (phosphine)-carbonylmetalate dianions and are extremely reactive. They quickly deprotonated acetonitrile to give essentially quantitative yields of HFe(CO)3(PR3)- and reacted with triphenylstannyl chloride to provide Ph3SnFe(CO)3(PR3)-. Ligand exchange reactions of K2[Fe(CO)3(PPh3)] with CO and P(OMe)3 readily occurred at room temperature and gave 80-90% isolated yields of K2[Fe(CO)4] and K2[Fe(CO)3(P(OMe)3)]. The latter salt contains the first isolated (phosphite)carbonylmetalate dianion and was characterized by elemental analyses and infrared spectra as a triphenyltin derivative, (Ph3Sn)Fe(CO)3(P(OMe)3)-. Treatment of [Et4N][HFe(CO)3(PPh3)] with hot ethanol provided low yields (ca. 10%) of the bridging phosphide salt [Et4N][Fe2(CO)6(μ-CO)(μ-PPh 2)]. Full details on the molecular structure of this anion, which has been mentioned previously in the scientific literature (Kyba, E. P.; Davis; R. E.; Clubb, C. N.; Liu, S. T.; Palacios, H. A. O.; McKennis, J. S., Organometallics 1986, 5, 869), are reported for the first time.

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.
