Higher generation cationic N,N-ruthenium(II)-ethylene-glycol-derived metallodendrimers: Synthesis, characterization and cytotoxicity

Paul Joseph Dyson, Tina Riedel

A new series of higher generation cationic N,N-chelating, ruthenium(II)-ethylene-glycol metallodendrimers from first-, second-, third- and fourth-generation pyridylimine-based poly(propylene) dendrimer scaffolds of the type, DAB-(NH2) (where n = 4, 8, 16 o ...

Chiral Cyclopentadienyl Ligands Enable a Rhodium(III)-Catalyzed Enantioselective Access to Hydroxychromanes and Phthalides

Nicolai Cramer, Baihua Ye

The demand for efficient chiral cyclopentadienyl ligands (Cp-x) has increased significantly in recent years, partly because Cp*Rh(III) species have been developed as powerful catalysts for directed C-H functionalization reactions. However, a lack of suitab ...

Chiral Cp-Rhodium(III)-Catalyzed Asymmetric Hydroarylations of 1,1-Disubstituted Alkenes

Nicolai Cramer, Baihua Ye, Pavel Alexandrovich Donets

Metal-catalyzed functionalizations at the ortho position of a directing group have become an efficient bond-forming strategy. A wide range of transformations that employ Cp*Rh-III catalysts have been described, but despite their synthetic potential, enanti ...

Ligand-Controlled Regiodivergent Pathways of Rhodium(III)-Catalyzed Dihydroisoquinolone Synthesis: Experimental and Computational Studies of Different Cyclopentadienyl Ligands

Nicolai Cramer, Matthew Wodrich, Jérôme Florian Gonthier, Baihua Ye

Rh-III-catalyzed directed C-H functionalizations of arylhydroxamates have become a valuable synthetic tool. To date, the regioselectivity of the insertion of the unsaturated acceptor into the common cyclometalated intermediate was dependent solely on intri ...

Contributions to the Chemistry of the Cyclopentadienyl Complex [Cp^RuCl2](2) ("Cp-roof" = eta(5)-1-Methoxy-2,4-tert-butyl-3-neopentylcyclopentadienyl)

Rosario Scopelliti, Kay Severin, Euro Solari, Barnali Dutta, Julie Risse

The dimeric ruthenium complex Cp^RuCl2 is easily accessible in a one-pot reaction from RuCl3(solv)(n) and tert-butylacetylene. It features sterically very demanding "Cp-roof" ligands (Cp^ = eta(5)-1-methoxy-2,4-tert-butyl-3-neopentylcyclopentadienyl), ...

Anionic Bipyridyl Ligands for Applications in Metallasupramolecular Chemistry

Rosario Scopelliti, Kay Severin, Mathieu Jérémie Marmier, Clément Schouwey, Mirela Pascu

The facile synthesis of anionic bipyridyl ligands with dinuclear clathrochelate cores is described. These metalloligands can be obtained in high yields by the reactions of M(ClO4)(2)(H2O)(6) (M: Zn, Mn, or Co) with 4-pyridylboronic acid and 2,6-diformyl-4- ...

Efficient and Rapid Synthesis of Chlorido-Bridged Half-Sandwich Complexes of Ruthenium, Rhodium, and Iridium by Microwave Heating

Rosario Scopelliti, Kay Severin, Zacharias Immanuel Grote, Julie Risse, Justus Tönnemann

The dinuclear complexes [(p-cymene)RuCl2]2 and [(cyclopentadienyl)MCl2]2 (M = Ru, Rh, Ir) are important starting materials in organometallic chemistry. The standard synthesis of these complexes involves heating of an alcoholic solution of RuIII, RhIII, or ...

Cytotoxicity of ruthenium-arene complexes containing B-ketoamine ligands

Paul Joseph Dyson, Rosario Scopelliti, Catherine Marie Amélie Clavel

New ruthenium(II) arene derivatives (arene = p-cymene, benzene, hexamethylbenzene) containing beta-ketoamine ligands L' (HL' in general; in detail, HLph,ph = (4Z)-3-methyl-4-((phenylamino)(phenyl)methylene)-1-phenyl-1H-pyrazol-5(4H)-one, HLnaph,ph = (4Z)-3 ...

Chiral Cyclopentadienyl Ligands as Stereocontrolling Element in Asymmetric C-H Functionalization

Nicolai Cramer, Baihua Ye

Metal complexes coordinated by a single cyclopentadienyl (Cp) ligand are widely used, versatile catalysts, but their application to asymmetric reactions has been hindered by the difficulty of designing Cp substituents that effectively bias the coordination ...
