Abstract

The reactions of [RuClH(CO)(BSD)(PPh₃)₂] (BSD = benzo-2,l,3-selenadiazole) with alkynes have been investigated and found to proceed readily with cis-hydroruthenation of the alkyne: The alkynes H-C≡C-R (R = H, ⁿC₄H₉, C₆H₄Me-4, CMe₂OH) provide simple 18-electron σ-E-vinyl complexes [Ru(CH=CHR)-Cl(CO)(BSD)(PPh₃)₂]; diphenylbutadiyne provides an α-(ethynyl)vinyl derivative [Ru{C(C≡CPh)= CHPh}Cl(CO)(BSD)(PPh₃)₂], whilst the propargylic ylide precursor HC≡C-CH₂CH(CO₂Et)PO(OEt)₂ yields the novel complex [Ru(CH=CH-CH₂CH(C0₂Et)PO(OEt)₂)Cl(CO)(BSD)(PPh₃)₂]. The BSD ligand in these complexes inhibits secondary insertion reactions but is sufficiently labile to be readily replaced by (2,6-dimethylphenyl)isonitrile to provide [Ru(vinyl)Cl(CO)(CNC₆H₃Me₂-2,6)(PPh₃)₂].
