Transition Metal Carbyne Complexes, XXXVIII: Carbyne Ligand Transfer by Reaction of Neutral and Cationic Carbyne Complexes with Octacarbonyldicobalt or Bis(π-cyclopentadienyl)nickeltrans-Halogenotetracarbonyl(organylcarbyne)chromium, -molybdenum, and -tungsten (1-3) or dicarbonyl(π-cyclopentadienyl)(phenylcarbyne)manganese tetrachloroborate (4) react with octacarbonyldicobalt under very mild conditions to give (π-alkyne)bis(tricarbonylcobalt)(Co—Co) (5) or (μ3-alkylidyne)-tris(tricarbonylcobalt)(Co—Co) (6). The reaction of bis(π-cyclopentadienyl)-nickel with trans-bromotetracarbonyl(phenylcarbyne)chromium (1b) under the same conditions yields (π-tolane)bis[(π-cyclopentadienyl)nickel](Ni—Ni) (7b). Besides that, traces of (μ3-benzylidine)-tris[(π-cyclopentadienyl)nickel] (Ni—Ni) (8b) could be identified by means of mass spectrometry.
Notes:
trans-Halogenotetracarbonyl(organylcarbin)chrom, -molybdän und -wolfram (1-3) oder Dicarbonyl(π-cyclopentadienyl)(phenylcarbin)mangan-tetrachloroborat (4) reagieren unter sehr milden Bedingungen mit Octacarbonyldicobalt zu (π-Alkin)bis(tricarbonylcobalt) (Co—Co) (5) oder (μ3-Alkylidin)-tris(tricarbonylcobalt)(Co—Co) (6). Mit Bis(π-cyclopentadienyl)nickel ergibt trans-Bromotetracarbonyl(phenylcarbin)chrom (1b) unter den gleichen Bedingungen (π-Tolan)-bis[(π-cyclopentadienyl)nickel] (Ni—Ni) (7b). Daneben konnte (μ3-Benzylidin)-tris[(π-cyclopentadienyl)nickel](Ni—Ni) (8b) massenspektrometrisch in Spuren nachgewiesen werden.
