摘要：

The reaction of 1,6-bis(trimethylsilyl)hexa-1,3,5-triyne (1) with Ru-3(CO)(12) results in the formation of the butterfly cluster Ru-4(CO)(12)(mu(4)-eta(1),eta(1),eta(2), eta(2)-Me3SiC=CC2C=CSiMe3) (2) and the yellow binuclear complex Ru-2(CO)(6) {mu-eta(2)-eta(4)-C(C=CSiMe3)=C(C=CSiMe3)C(C=CSiMe3)=C(C=CSiMe3)} (3) Both complexes contain pendant ethynyl ligands that are potential sites for further reactivity. In the case of reaction of 1 with the tetranuclear cluster Ru-4(mu(4)-PPh)(CO)(13) (4), the open chain molecule Ru-4(CO)(8)(mu(3)-PPh)[mu(4)-eta(2),eta(4),eta(2),eta(4)-(Me3SiC=C)CC(C=CSiMe3)C(C=CSiMe3)C-CC(SiMe3)C(C=CSiMe3)C(C=CSiMe3)] (6) is formed, in which the co-ordination of a pendant ethynyl moiety has been realised.
