Synthesis of Chiral Bifunctional (Thio)Urea N-Heterocyclic Carbenes

Jérôme Waser, Jonathan Brand, Jose Ignacio Osuna Siles

The rapid and modular synthesis of the first bifunctional N-heterocyclic carbenes bearing a (thio)urea moiety as H-bond donor group was reported. Different analogues could be accessed in seven steps from cheap (S)-pyroglutamic acid in good overall yields ( ...

Synthesis and characterisation of the water soluble bis-phosphine complex [Ru(η6-cymene)(PPh2(o-C6H4O)-κ2-P,O)(pta)]+ and an investigation of its cytotoxic effects

Paul Joseph Dyson, Rosario Scopelliti, Christian Hartinger, Anna Katherine Renfrew

Metal complexes bearing phosphine ligands are attracting increasing attention for their applications in medicinal chem. In particular, organometallic ruthenium-phosphine complexes have been found to exhibit promising antitumor activity. The synthesis, anti ...

Cross Coupling of Non-Activated Alkyl Halides by a Nickel Pincer Complex

Xile Hu

Non-activated alkyl halides are challenging substrates for cross-coupling reactions because they are reluctant to undergo oxidative addition and because metal alkyl intermediates are prone to β-H elimination. Despite recent progress, well-defined catalysts ...

Chelating NHC Ruthenium(II) Complexes as Robust Homogeneous Hydrogenation Catalysts

Gabor Laurenczy, Antonia Neels

A series of ruthenium(II) N-heterocyclic carbene chelate complexes were prepd. by using bidentate chelating alkene-carbene, thioether-carbene, carboxylate-carbene and bis-carbene ligands. Metalation of 1-R-3-X-imidazolium salts (1-3, R = Me, X = allyl, MeS ...

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...

Structured fiber supports for ionic liquid-phase catalysis used in gas-phase continuous hydrogenation

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Marina Ruta

Structured supported ionic liquid-phase (SSILP) catalysis is a new concept with the advantages of ionic liquids (ILs) used as solvents for homogeneous catalyst and the further benefits of structured heterogeneous catalysts. This is achieved by confining th ...

Catalytic Activity of Bis-phosphine Ruthenium(II)-Arene Compounds: Chemoselective Hydrogenation and Mechanistic Insights

Paul Joseph Dyson

Bis-phosphine Ru(II)-arene complexes are highly active and chemoselective catalysts for the hydrogenation of aldehydes in the presence of olefinic bonds. Mechanistic studies, including comparisons with a structural analog, reactions of an isolated hydride ...
