Influence of Functionalized η6 -Arene Rings on Ruthenium(II) Curcuminoids Complexes

Paul Joseph Dyson, Rosario Scopelliti, Tina Riedel, Agnese Petrini

A series of organometallic Ru(II) complexes containing functionalized η6‐arene ligands, together with curcumin and bisdemethoxycurcumin as O,O’‐chelating ligands and their RAPTA (ruthenium arene complexes bearing the 1,3,5‐triaza‐7‐phosphaadamantane ligand ...

CO2 as hydrogen vector - Transition metal diamine catalysts for selective HCOOH dehydrogenation

Gabor Laurenczy, Cornel Fink

The homogeneous catalytic dehydrogenation of formic acid in aqueous solution provides an efficient in situ method for hydrogen production, under mild conditions, and at an adjustable rate. We synthesized a series of catalysts with the chemical formula [Cp* ...

Synthesis and Photophysical Characterization of Cyclometalated Ruthenium Complexes with N-Heterocyclic Carbene Ligands

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Sadig Aghazada, Valeriu Scutelnic

In the search of new ligand environment for the ruthenium(II) complexes with pyridine-type ligands, we developed seven new cyclometalated ruthenium complexes with N-heterocyclic carbenes (NHCs). In a two-step procedure, we synthesized complexes with the ge ...

Development of Site-Specific Mg2+-RNA Force Field Parameters: A Dream or Reality? Guidelines from Combined Molecular Dynamics and Quantum Mechanics Simulations

Ursula Röthlisberger, Giulia Palermo

The vital contribution of Mg2+ ions to RNA biology is challenging to dissect at the experimental level. This calls for the integrative support of atomistic simulations, which at the classical level are plagued by limited accuracy. Indeed, force fields intr ...

Neutral chiral cyclopentadienyl Ru(II)Cl catalysts enable enantioselective [2+2]-cycloadditions

Nicolai Cramer, David Kossler

Cyclopentadienyl ruthenium(II) complexes with a large number of available coordination sites are frequently used catalysts for a broad range of transformations. To be able to render these transformations enantioselective, we have designed a chiral neutral ...

Cytotoxicity of arene ruthenium metalla-rectangles incorporating bis-pyridyl diimide linkers

Paul Joseph Dyson, Tina Riedel

A series of tetranuclear arene ruthenium complexes of the general formula [Ru-4(p-cymene)(4)(mu(2)-L)(2)(mu(4)-OO boolean AND OO)(2)]CF3SO3 (L-1 = N,N'-bis(4-pyridylmethyl)-pyromellitic diimide, L-2 = N,N'-bis(4-pyridylmethyl)-naphthalene diimide) wer ...

Synthesis, structural determination, theoretical studies and catalytic activity of Mn(II) complex of N-isonicotinyl phosphoric triamide ligand

Farzaneh Fadaei Tirani, Kurt Schenk

synthesized and characterized by H-1, C-13, P-31 NMR and IR spectroscopies. The reaction of MnCl2 center dot 4H(2)O with L led to the formation of a new 3D system {MnL2Cl2}(n)center dot 34CH(3)OH (C-1). X-ray crystallographic data revealed that the ligand ...

Supramolecular assemblies of organotin(IV)-diphosphoryl adducts: insights from X-rays and DFT

Kurt Schenk

Mono-, di- and tri-phenyltin(IV) adducts containing a neutral diphosphoryl ligand, Ph2P(O)OC6H4OP(O) Ph-2, were synthesized and characterized. These 2 : 1 adducts of two trans-organotin(IV) moieties and the bridging ligand all crystallize around a centre o ...
