摘要：

In the presence of catalytic amount of bis(acetonitrile)dichloropalladium(II) [(CH3CN)(2)PdCl2] the iodocyclopentadienylmetal complexes [(eta(5)-C5H5)M(CO)(n)I](1, M = Mo, n = 3; 2, M = W, n = 3; 3, M = Fe, n = 2, 4, M = Ru, n = 2) couple in a 2 to 1 ratio with 2,5-bis[(tributyltin)ethynyl]thiophene (5), to form the corresponding dimetal derivatives of general formula [(mu-C4H2SC=C-2,5){(C5H5)M(CO)(n)}(2)] (6, M = Mo, n = 3; 7, M = W, n = 3; 8, M = Fe, n = 2; 9, M = Ru, n = 2).
