  摘要：

  The reaction between (eta(5)-C5H4I)Fe(CO)(2)CH3 (2) and 2,5-bis[(trimethylstannyl)ethynyl]thiophene in the presence of palladium affords the iron dimer CH3(CO)(2)Fe(eta(5)-C5H4)C=CC=CHSCH=CC=C(eta(5)-C5H4)Fe(CO)(2)CH3 (4), which upon treatment with I-2 is transformed to the corresponding diiodide I(CO)(2)Fe(eta(5)-C5H4)C=CC=CHSCH=CC=C(eta(5)-C5H4)Fe(CO)(2)I (5). Re action of the latter, in the presence of palladium, with the (trimethylstannyl) acetylide derivatives LnM(eta(5)-C5H4)C=CC=CHSCH=CC=CSn(CH3)(3) (9a, MLn = W(CO)(3)CH3, 9b, MLn = Re(CO)(3)) affords the polymetallaacetylide tethers LnM(eta(5)-C5H4)C=CC=CHSCH=CC=CFe-(CO)(2)(eta(5)-C5H4)C=CC=CHSCH=CC=C(eta(5)-C5H4)(CO)(2)FeC=CC=CHSCH=CC=C(eta(5)-C5H4)-MLn (10, MLn = W(CO)(3)CH3; 11, MLn = Re(CO)(3)). Trimethyltin derivatives of poly(ethynylthiophene) oligomers have been also prepared and tested for their use as spacers in poly(metallaacetylide) complexes.
