Abstract

The synthesis of the first example of a bime-tallic complex spanned by the C₄H alkynylvinylidene ligand, [Cl(CO)₂L ₂RuC≡CCH=C-RuL₂(η-C₅H ₅]PF₆ (L = PPh₃), is reported: the reaction of [Ru(CO)₂L₃] with butadiyne provides [RuH(C≡CC≡ CH)(CO)₂L₂], which is converted to the chloro derivative [RuCl(C≡CC≡CH)-(CO)₂L₂] by N-chlorosuccinimide. Subsequent treatment with [Ru(thf)L₂(η- C₅H₅)]PF₆ provides [Cl(CO)₂L ₂RuC≡ CCH=C=RuL₂(η-C₅H ₅)]PF₆, deprotonation of which affords [Cl(CO) ₂L₂RuC≡CC≡CRuL₂(η-C ₅H₅)].
