摘要：

Reactions of butadiynediyldimetal complexes, Fp*-C=C-C=C-M(eta(5)-C5R5)(CO)(2) 1 [M = Fe, Ru; R = Me, H; Fp* = FeCp*(CO)(2)], with group 8 metal carbonyls result in migration of a sigma-bonded metal fragment along the C-4 rod to form novel highly conjugated polycarbon-metal systems; the zwitterionic mu-but-2-yn-1-ylidene-4-ylidyne complex Ru-3(CO)(10)(mu(3)-C-C=C-mu-C)Fe2Cp2*(CO)(3) 2, and the dimerized product with a cumulenic mu-C-8 ligand (Cp*Fe)(4)-Ru-2(CO)(13)[mu(6)-C-8-C(=O)] 3, via 1,4-migration and the zwitterionic acetylide cluster-type product Fp(*+)[Cp(CO)(2)Ru-(eta(2)-C=C)-(mu(3)-C=C)Fe-3(CO)(9)](-) 4, via 1,3-migration.
