摘要：

(eta(5)-C(5)Me(5))(PPh(3))(2)Ru(Cl) (1) reacted with HC=CSiMe(3) in the presence of NH4PF6 to afford the cationic Ru(ll) terminal vinylidene complex, [(eta(5)-C-5-Me(5))(PPh(3))(2)Ru(=C=CH2)]/PF6 (2), in 73% yield. The terminal vinylidene complex 2 was doubly deprotonated with t-BuLi to generate the reactive lithioacetylide complex, (eta(5)-C(5)Me(5))(PPh(3))(2)Ru(C=CLi) (4), which was trapped with Me(3)SiCl and MeI to give (eta(5)-C(5)Me(5))(PPh(3))(2)- Ru(C=CSiMe(3)) (5) and (eta(5)-C(5)Me(5))(PPh(3))(2)Ru(C=CMe) (6) in 86 and 39% yields, respectively. The molecular structures of 2 and 5 were determined by X-ray crystallography.
