    • Abstract


      The complexes [CpRuL2Cl] (L=PPh3, AsPh3, SbPh3) react with the phenylacetylene,γ-hydroxyacetylenes HC≡CCR1R2OH (R1=R2=H, Me, and R1=Me, R2=Et; CR1R2OH=1-hydroxycyclohexanol) and NaBF4 in methanol, to yield complexes of the typeη1-vinylidenes [CpL2Ru+(=C=CHR)],η1- allenylidene [CpL2Ru+ (=C=C=CR1R2)], and dimeric allenylidene-vinyl and vinylidene-alkylidene complexes. Theseη1-vinylidene andη1-allenylidene complexes are reversibly deprotonated by sodium borohydride in methanol to yield the correspondingη1-alkynyl complexes [CpL2Ru(C≡CR)].
