Triorganosilanes react with dodecacarbonyltriruthenium to give complexes [R3SiRu(CO)4]2(I). When R = Me the compound (Me3Si)2Ru(CO)4(II) is also obtained. Complexes (I) are air-stable crystalline compounds which probably contain the linear sequence Si·Ru·Ru·Si. Treatment of (I; R = Me) with sodium amalgam affords the anion [Me3SiRu(CO)4]– which has been used to prepare Me3SiRu(CO)4X (X = Me3Sn, Ph3Sn

[Ru2(SiMe3)2(CO)4(C8H5R)] in moderate yield. Under mild conditions (hexanereflux)[Ru(GeMe3)2(CO)4] with cyclo-octatetraene yields small amounts of [Ru(GeMe3)(CO)2C8H8(GeMe3)}] whereas [Ru(SiMe3)(GeMe3)(CO)4] readily gives [Ru(GeMe3)(CO)2C8H8(SiMe3)}]. In heptane or octane [Ru(GeMe3)2(CO)4] undergoes more complex reactions, affording [Ru(GeMe3)(CO)2(C8H9)], [Ru2(GeMe3)2(CO)4(C8H8)], and [Ru2(GeMe3)2(CO)4(C8H6)]

Reactions of [Ru(SiMe3)(CO)21–3;6–7-η-C8H7(SiMe3)2–5,8}] with the same reagents give only the pentalene complexes [Ru3(CO)8C8H6–n(SiMe3)n}](n= 0–3), but in increased yields. Heterodimetallic complexes [FeRu(SiMe3)(CO)5(C8H8SiMe3)] and [MnRu(CO)7(C8H7)] are obtained on treating [Ru(SiMe3)(CO)21–3;6–7-η-C8H8(8-endo-SiMe3)}] with [Fe2(CO)9] or [MnMe(CO)5], respectively
