    Notes: Summary Phenylacetylene reacts stoichiometrically or in excess with the Ru—H bond of RuH(CO)(PPh3)2(L) (LH = 2-hydroxypyridine, 2-hydroxy-6-methylpyridine, acetylacetone, benzoylacetone, 2-hydroxyacetophenone, 2-hydroxypropiophenone, 2-hydroxybenzophenone and 4-methoxy-2-hydroxybenzophenone) in boiling benzene to give σ-vinylic or σ-vinylalkynyl complexes of the type Ru(CO)-(PPh3)2(L)(CH $$ = $$ CHPh) and Ru(CO)(PPh3)2(L){C-(C $$ \equiv $$ CPh) $$ = $$ CHPh} in good yield. The vinylic complex can also be obtained by reacting the sodio derivative of the chelating ligand with the 16e− unsaturated complex, [Ru(CO)Cl(CH $$ = $$ CHPh)(PPh3)2], in CH2Cl2/MeOH mixture at ambient temperature. These complexes have been characterized by elemental analyses, and i.r., 1H, 13C and 31P n.m.r. spectroscopy.

    Schiff base complexes of ruthenium(II) with tridentateN-methyl-S-methyldithiocarbazate ligands (1987)
    Springer
    Transition metal chemistry 12 (1987), S. 414-417 
    Details
    ISSN: 1572-901X

    Topics: Chemistry and Pharmacology
    Notes: Summary Schiff bases (HL) produced by the condensation ofN-methyl-S-methyldithiocarbazate with β-diketones and aromatic aldehydes or ketones react with [RuHClCO(PPh3)3] to yield hexacoordinated complexes of the type [RuClCO(PPh3)2(L)]. These Schiff bases react with [RuCl2{P(OR)3}4] in 1∶1 molar ratio to yield [RuCl{P(OR)3}2(L)] in which L is a tridentate. The chlorine atom in the complex can be removed in coordinating solvents in the presence of anions such as [BPh4]− to give cationic complexes. Bis chelate complexes, [Ru{P(OR)3}2(L)2] are prepared from 1∶2 molar proportions of the reactants. These complexes were characterised by elemental analyses, i.r.,1H n.m.r., u.v. and conductivity studies.

    Octahedral ruthenium(II) alkenyl complexes containing $${\text{N}}{\text{S}}$$ coordinated heterocyclic ligands (1993)
    Springer
    Transition metal chemistry 18 (1993), S. 585-587

    Topics: Chemistry and Pharmacology
    Notes: Summary Hexacoordinated ruthenium(II) alkenyl complexes of the type Ru(CO)(CR=CHPh)( $${\text{N}}{\text{S}}$$ )(PPh3)2 have been prepared from coordinately unsaturated σ-vinyl complexes [Ru(CO)Cl(CR=CHPh)(PPh3)2] (R = H or Ph) and the sodio-derivative of the $${\text{N}}{\text{S}}$$ containing heterocyclic ligands [ $${\text{N}}{\text{S}}$$ = 3,4-substituted 1,2,4-triazole-5-thione and 5-alkylthio-1,3,4-thiadiazole-2-thione] in a CH2Cl2/MeOH mixture at ambient temperature. The complexes were characterized by their elemental analysis, i.r., 1H and 31P n.m.r. spectra. An octahedral structure with transphosphorus ligands has been assigned on the basis of the spectral data.
