(American Chemical Society, 2015-04)
The syntheses and structural characterizations of a Pt–Tl chain [{Pt(bzq)(C6F5)2}Tl(Me2CO)]n 1 and two trinuclear Pt2M clusters (NBu4)[{Pt(bzq)(C6F5)2}2Tl] 2 and [{Pt(bzq)(C6F5)2}2Pb] 3 (bzq = 7,8-benzoquinolinyl), stabilized ...
Mono and dimetallic pyrene-imidazolylidene complexes of iridium (III) for the deuteration of organic substrates and the C-C coupling of alcohols
(Royal Society of Chemistry, 2016)
Three different Ir(III) complexes with pyrene-containing N-heterocyclic carbenes have been prepared and
characterized. Two complexes contain a monodentate pyrene-imidazolylidene ligand, and have the formulae
[IrCp*Cl2( ...
Mechanistic implications of the enantioselective addition of alkylzinc reagents to aldehydes catalyzed by nickel complexes with a-amino amide ligands
(The Royal Society of Chemistry, 2016-11)
The enantioselective alkylation of aldehydes catalysed by nickel(II)-complexes derived from α-amino amides was studied by means of density functional theory (DFT) and ONIOM (B3LYP:UFF) calculations. A mechanism was proposed ...
Interactions of long-chain homologues of colchicine with tubulin
(Elsevier, 2017-01)
Several colchicine analogues in which the N-acetyl residue has been replaced by aliphatic, straight-chain acyl moieties, have been synthesized. These compounds show high cytotoxic activity at the nanomolar level against ...
Supramolecular Interactions Based on Ionic Liquids for Tuning of the Catalytic Efficiency of (L)-Proline
(American Chemical Society, 2016-09)
Noncovalent intermolecular interactions between (l)-proline and ionic liquids (ILs) are key to explain the different catalytic efficiencies observed for this organocatalyst in the aldol reaction carried out in ILs or in ...
Magnetism and Heterogeneous Catalysis: In Depth on the Quantum Spin-Exchange Interactions in Pt3M (M = V, Cr, Mn, Fe, Co, Ni, and Y)(111) Alloys
(American Chemical Society, 2020-11-11)
Bimetallic Pt-based alloys have drawn considerable attention in the last decades as catalysts in proton-exchange membrane fuel cells (PEMFCs) because they closely fulfill the two major requirements of high performance and ...
Chemoenzymatic synthesis of optically active 2-(2- or 4-substituted-1H-imidazol-1-yl)cycloalcanols. Chiral additives for (L)-proline
(Royal Society of Chemistry, 2013-04-03)
Enantiopure substituted imidazoles obtained by enzymatic kinetic resolution can be promising candidates as co-catalysts for aldol reactions catalysed by (L)-proline. These additives seem to form supramolecular complexes ...
