The reaction of a conjugated enyne, cis-(Me3Si)CH= CHC≡CSiMe3, with [RuCl(CO)H(PPh3)3] gives a quantitative yield of a stable complex whose molecular structure is formally regarded as the result of either 1,2-addition of the H-Ru to the double bond or 1,4-addition of the H-Ru to the conjugated enyne; the former bonding scheme operates when the enyne is hydrogenated by [Ru(CO)H2 (PPh 3)3] or [RuH2(PPh3)4], the sole product being Me3SiCH2CH2C≡ CSiMe3.
