“…The two products are quite different, but in each case, the alkyne has formally inserted into the iron−alkenyl σ-bond. But-2-yne only affords the ferracycle product 234b . (Note that 233 is related to 147 ; the alkenyl is π-bonded to the tungsten atom in 233 but to the iron in 147 ).…”

ChemInform Abstract: Polynuclear Metal Complexes with Bridging Carbene or Carbyne Ligands. Part 81. Reactions of the Compound (Fe2(μ‐CH2)(CO)8) with Alkylidyne‐Molybdenum and ‐Tungsten Complexes. Reactivity of the Product (WFe(.mu±sigma.:η‐CH=CH(C6H4Me‐4))(CO)6(η‐C5H5)), and Crystal Structures of the Species (W2Fe(μ3‐CC6H4Me‐4)(.mu±sigma.:η‐C(C6H4Me‐4)=CH2)(CO)6(η‐C5H5)2) and (WFe(μ‐C(Et)C(Et)C(H)CH(C6H4Me‐4))(μ‐CO)(CO)4(η‐C5H5)).

ChemInform Abstract Treatment of the dinuclear title Fe compound (I) with the alkylidyne complexes (II) affords the complexes (III) as the main products. Additional to (IIIb) the µ3-p-tolyl-methylidyne-W2Fe complex (IV) and to (IIIc) the µ3-propylidyne-Fe2W complex (V) nd the known W2Fe(µ3-MeC≡ CMe)(CO)6Cp2 are obtained. Some reactions of the complex (IIIb) with tert. phosphines (PPh3, PMe3, Ph2PCH2PPh2, Me2PCH2PMe2), alkynes (3-hexyne, 2-butyne) and the Pt reagent Pt(CH2=CH2)2P(C6H11)3 are studied. They lead o the products (VI)-(IX). All the products obtained are characterized spectroscopically (IR, 1H, 13C NMR). The structures of (IV) (space group P21/c, Z=4) and (VIIIa) (C2/c, Z = 8) are established by X-ray analysis.
