(η5-C5Me5)(PPh3)2Ru(Cl) (1) reacted with HC⋮CSiMe3 in the presence of NH4PF6 to afford the cationic Ru(II) terminal vinylidene complex, [(η5-C5Me5)(PPh3)2Ru(CCH2)]PF6 (2), in 73% yield. The terminal vinylidene complex 2 was doubly deprotonated with t-BuLi to generate the reactive lithioacetylide complex, (η5-C5Me5)(PPh3)2Ru(C⋮CLi) (4), which was trapped with Me3SiCl and MeI to give (η5-C5Me5)(PPh3)2Ru(C⋮CSiMe3) (5) and (η5-C5Me5)(PPh3)2Ru(C⋮CMe) (6) in 86 and 39% yields, respectively. The molecular structures of 2 and 5 were determined by X-ray crystallography.
