Abstract

The synthesis of vinylidene, trans-[(dppm)₂ClMCC(H)(R)]PF₆, and σ-acetylide complexes, trans-[(dppm)₂ClMCCR] (M = Ru, Os; dppm = bis(diphenylphosphino)methane, Ph₂PCH₂PPh₂; R = p-C₆H₅, p-C₆H₄C₆H₅, p-C₆H₄₂, C₆H₃2-(CH₃)-4-NO₂, p-C₆H₄CH₃), and a single-crystal X-ray determination of trans-[(dppm)₂ClRuCCC₆H₄-p-NO₂] are reported. The metal-phosphine fragment in these complexes acts as a donor and communicates with the para-substituted nitro acceptor group through the backbone. Such an interaction helps create a delocalized charge-transfer state from the donor to the acceptor.
