“…Ruthenium hydride complexes of carbonyl and triarylphosphine ligands are interesting due to their reactivity and efficiency as catalysts in a wide variety of reactions [1][2][3][4][5][6]. The synthesis and characterization of ruthenium complexes containing nitrogen heteroaromatic ligands have also received considerable recent attention, owing to their interesting photophysical and photochemical properties.…”

The reaction of [RuHCl(CO)(PPh 3 ) 3 ] with 4-phenylpyrimidine gave a new ruthenium(II) complex, namely [RuHCl(CO)(PPh 3 ) 2 (pyrim-4-Ph)]. The complex has been studied by IR and UV-vis spectroscopy and by X-ray crystallography. The molecular orbitals of the complex have been calculated by density functional theory. The spin-allowed singlet-singlet electronic transitions of the complex have been calculated by time-dependent DFT, and the UV-vis spectrum of the compound has been discussed on this basis. The emission properties of the complex were also studied.

“…On the other hand, among the transition metals, the ruthenium complexes have received considerable attention due to their reactivity and efficiency as catalysts in wide spectrum of reactions [25][26][27][28][29][30]. Stimulated by the success of both Schiff bases and ruthenium complexes in catalytic activity, we have combined both types to prepare two new classes of hydroxyquinolineSchiff base ligands and their ruthenium complexes.…”

New octahedral ruthenium(II) complexes (1-4) have been synthesized from the reaction of ruthenium(II) precursors [RuHCl(CO)(EPh 3 ) 3 ] (E = P or As) with the bidentate Schiff base ligands, 2-((2,6-dimethylphenylimino)methyl)quinolin-8-ol (L 1 ) and 2-((2,6-diisopropylphenylimino)methyl)quinolin-8-ol (L 2 ) in ethanol. These complexes have been characterized by elemental analyses, IR, UV-Vis, 1 H, 13 C and 31 P NMR and ESI-Mass spectroscopy. The molecular structure of the complex [RuCl(CO)(PPh 3 ) 2 (L 2 )] (2) was determined by single-crystal X-ray diffraction, which reveals a distorted octahedral geometry around ruthenium(II) ion. The catalytic activity of the new complexes was evaluated for the condensation of nitriles with ethanolamine under solvent free conditions. The processes were operative with aromatic and heteroaromatic nitriles and tolerated several substitutional groups.The studies on the effect of substitution over ligands, coligands, reaction time, temperature and catalyst loading were carried out in order to find the best catalyst in this series of complexes and favorable reaction conditions. A probable mechanism for the catalytic condensation of nitrile has also been proposed. The catalyst was recovered and recycled up to five times without significant loss of its activity.

“…Of these complexes, ruthenium hydride containing carbonyl and triarylphosphine ligands have attracted enough attention due to their reactivity and efficiency as catalysts in hydrogenation reactions of unsaturated substrates, hydrogen transfer, activation of C-H bonds, and isomerization reactions [2][3][4][5][6][7][8][9].…”
