Cyclopentadienyl-Ruthenium and -Osmium Chemistry. XXIII Synthesis and Reactions of Some Hydrido Complexes Containing Ruthenium or Osmium, and Related Chemistry

Abstract

The hydrido complexes HM(PPh3)2(η-C5H5) (M = Ru, Os), HFe(dppe) (η-C5H5), HRu(L2)(η-C5H5) (L2 = dppe, dppmordpae), HRu(AsPh3)2(η-C5H5), HRu(L)(PPh3)(η-C5H5) [L = CNBut, P(OPh)3] have been obtained from reactions between the analogous chloro complexes and NaOMe/MeOH; RuCl[P(OPh)3]2(η-C5H5) affords the cyclometallated under these conditions. Reactions between HRu(PPh3)2(η-C-H5) and HX or CHX3 (X = Cl, Br, I) afford the corresponding halo complexes RuX(PPh3)2(η-C5H5); CS2 reacts with HRuL2(η-C5H5) (L = PPh3, L2 = dppe) to give the corresponding dithioformato derivatives. Ligand-exchange reactions of HRu(PPh3)2(η-C5H5) with CO or dppe proceed with difficulty at temperatures of c. 150-200°C in an autoclave. Show more
