  • Alkynyl and poly-ynyl derivatives of carbon-tricobalt clusters

    Antonova, Alla B.; Bruce, Michael I.; Humphrey, Paul A.; Gaudio, Maryka; Nicholson, Brian K.; Scoleri, Nancy; Skelton, Brian W.; White, Allan H.; Zaitseva, Natasha N. (Elsevier S.A., 2006-04-01)
    A series of alkynyl-tricobalt carbonyl clusters, Co₃(μ₃-CnR)(μ-dppm)(CO)₇ [R = But, Ph, C₆H₄I, C₆H₄C≡CPh, SiMe₃, Fc, Au(PPh₃)] containing three, five or seven carbons in the chain, have been prepared by elimination of ...
  • Conversion of C≡C to CO in alkynyl-metal complexes: oxidation of carbon chains capped by carbon-tricobalt clusters

    Bruce, Michael I.; Humphrey, Paul A.; Zaitseva, Natasha N.; Nicholson, Brian K.; Skelton, Brian W.; White, Allan H. (The Royal Society of Chemistry, 2010)
    Treatment of Co₃(μ₃-CC≡CR)(μ-dppm)(CO)₇ with O₂ (air) in the presence of [FcH]PF₆ afforded Co₃{μ₃-CC(O)R}(μ-dppm)(CO)₇ by the formal conversion –C≡C– + O–O → >C–O + C≡O. In this way, complexes with R = Ph, Fc, and W(CO)₃Cp, ...
