Immobilized Rh, Ru, Pd and Ni complexes as catalysts in the hydrogenation of cyclohexene
(Elsevier Science, 2004-10)
Complexes of Rh, Ru, Pd and Ni with tridecylamine and chloride as ligands were prepared and tested as heterogeneous catalysts for the hydrogenation of cyclohexene. The Wilkinson's complex was used as a reference catalyst. ...
1-Heptyne semihydrogenation catalized by palladium or rhodium complexes. Influence of: metal atom, ligands and the homo/heterogeneous condition
(Elsevier Science, 2007-07)
[RhCl(TDA)3], [RhCl(HA)3], [PdCl2(TDA)2] and [PdCl2(HA)2] (TDA = tridecylamine, HA = hexylamine) were synthesized and tested as catalysts in homogeneous and heterogeneous condition for the 1-heptyne semihydrogenation, using ...
Group VIII transition metal complexes with the chiral diphosphazane ligand (S)-alpha-(Ph2P)(2)N(CHMePh): Synthesis and structural characterization
(ELSEVIER SCIENCE SA, 2006)
The chiral ligand S-(Ph2P)(2)N(CHMePh) reacts with Ni(CO)(4) in benzene solution to yield the mononuclear complex [Ni(CO)(2)]{kappa(2)-(PPh2)2N(CHMePh))] (1). The reactions of the chiral ligand with the solvated complexes ...
Graphite oxide as a support for palladium and rhodium complexes, assessed as catalysts for the partial hydrogenation of 1-heptyne
(MedCrave, 2020-08)
Graphite oxide (GO) was used to anchor [PdCl2(TDA)2] and [RhCl(TDA)3] (TDA = NH2(CH2)12CH3) with 2wt % of metal load. Elemental analysis (EA), FTIR, XPS, XRD and atomic absorption spectroscopy (AA) were the techniques ...
Adsorption of NO on the Rh-13, Pd-13, Ir-13, and Pt-13 Clusters: A Density Functional Theory Investigation
(AMER CHEMICAL SOCWASHINGTON, 2012)
The adsorption of NO on transition-metal (TM) surfaces has been widely studied by experimental and theoretical techniques; however, our atomistic understanding of the interaction of nitrogen monoxide (NO) with small TM ...
First- and second-row transition metal oxa-aza macrocyclic complexes: a DFT study of an octahedral conformation
(SPRINGERNEW YORK, 2012)
A theoretical study of structures of the 1,7,1 l,17-tetraoxa-2,6,12,16-tetraaza-cycloeicosane ligand ([20]AneN(4)O(4)) coordinated to Fe2+, Co2+, Ni2+, Ru2+, Rh2+, and Pd2+ transition metals ions was carried out with the ...
