K2[cis-Mo(CO)4(PPh2)2] and [NEt4]Br. No carbyne-carbonyl coupling is observed in these reactions. Oxidation of 1a with PhICl2 and 1b with Br2 in 1,2-dimenthoxyethane (DME) affords after elimination of all CO ligands the 16-electron aminocarbyne complexes mer-X3(DME)W≡CNiPr2 (X = Cl (15a) or Br (15b)). In comparison, oxidation of 11–13 with PhICl2 yields the 18-electron aminocarbyne complexes Cp(Cl)2(CO)W ≡ CNR2
