Alkynyl and poly-ynyl derivatives of carbon-tricobalt clusters
(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 ... -
Bis(metallaethynyl) Ketones: Synthesis and Structure of {(Ph₃P)AuC≡C}₂CO and Attempted Transmetalation: Formation and Structure of [1,3-{Ru(dppe)Cp}₂{c-COC(OMe)CHCCH}]PF₆
(American Chemistry Society, 2011)The bis(metallaethynyl) ketone {(Ph₃P)AuC≡C}₂CO (1), obtained from (Me₃SiC≡C)₂CO, AuCl(PPh₃), and NaOMe, forms an Au•••Au-bonded dimer in the solid state (Au•••Au = 2.9825(3) Å). The ES-MS contains ions [2M + X]⁺ (X = Na, ... -
Conversion of C≡C to CO in alkynyl-metal complexes: oxidation of carbon chains capped by carbon-tricobalt clusters
(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, ... -
A Percyanovinylidene−Ruthenium Complex, Ru{═C═C₅(CN)₃[═C(CN)₂]₂}(dppe)Cp*
(American Chemical Society, 2011)The reaction between Ru(C≡CC≡CAg)(dppe)Cp* and tcne affords a novel percyanovinylidene complex by an unusual decyano-dimerization reaction of the cyanocarbon with the diynyl fragment. This complex is also obtained from ... -
Polarized Complexes Obtained by Regiospecific Substitution of a CN Group in Ru{C≡CC(CN)═C(CN)₂}(dppe)Cp* (Cp* = η-C₅Me₅)
(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, ...
