  • Polarized Complexes Obtained by Regiospecific Substitution of a CN Group in Ru{C≡CC(CN)═C(CN)₂}(dppe)Cp* (Cp* = η-C₅Me₅)

    Bruce, Michael I.; Burgun, Alexandre; Nicholson, Brian K.; Parker, Christian R.; Skelton, Brian W.; White, Allan H. (American Chemistry Society, 2012)
    The complex Ru{C≡CC(CN)═C(CN)₂}(dppe)Cp* (1), containing the new tricyanovinylethynyl (3,4,4-tricyanobut-3-en-1-ynyl) ligand, undergoes ready substitution of the 3-cyano group by nucleophiles (Nu) such as H, Me, Pri, Bu, ...
  • Some Ruthenium Derivatives of Penta-1,4-diyn-3-one

    Bruce, Michael I.; Burgun, Alexandre; Fox, Mark A.; Jevric, Martyn; Low, Paul J.; Nicholson, Brian K.; Parker, Christian R.; Skelton, Brian W.; White, Allan H.; Zaitseva, Natasha N. (ACS Publishing, 2013)
    The reaction between Ru(C≡CH)(dppe)Cp* (1) and oxalyl chloride affords ({Ru(dppe)Cp*}C≡C)₂CO (2) in 72% yield. Methylation (MeOTf) of 2 occurs first on the carbonyl oxygen, affording [({Ru(dppe)Cp*}C≡C)2C(OMe)]OTf ([3]OTf). ...
  • Syntheses and structural studies of several diynyl-ruthenium complexes and their adducts with cyano-alkenes

    Bruce, Michael I.; Burgun, Alexandre; Grelaud, Guillaume; Jevric, Martyn; Nicholson, Brian K.; Skelton, Brian W.; White, Allan H.; Zaitseva, Natasha N. (Wiley, 2011)
    Herein are described some continuing investigations into the reactions of cyano-alkenes with diynyl-ruthenium complexes which have resulted in the preparation and characterisation of diynyl-ruthenium compounds Ru(C≡CC≡CR)(PP)Cp ...
  • Tricyanovinylalkynyl–metal complexes: synthesis and some reactions

    Bruce, Michael I.; Burgun, Alexandre; Kramarczuk, Kathy A.; Nicholson, Brian K.; Parker, Christian R.; Skelton, Brian W.; White, Allan H.; Zaitseva, Natasha N. (Royal Society of Chemistry, 2008)
    Reactions of Group 8 metal ethynyls with tetracyanoethene afford tricyanovinylethynyl–metal derivatives, M{C≡CC(CN)=C(CN)2}(PP)Cp’ [2; M = Ru, Os; PP = (PPh3)2, dppe;Cp’=Cp,Cp*; not all combinations]; a similar reaction ...
