Mono- and dinuclear gold complexes with N-heterocyclic carbene (NHC) ligands have been employed as catalysts in the intermolecular hydroarylation of alkynes with simple unfunctionalised arenes. Both mono- and dinuclear gold(III) complexes were able to catalyze the reaction; however, the best results were obtained with the mononuclear gold(I) complex IPrAuCl. This complex, activated with one equ...

Dinuclear rhodium complexes are attractive candidates as homogeneous panchromatic photosensitizers and photocatalysts. Modification of the coordination sphere Rh2(II,II) compounds results in photophysical redox properties that highly desirable for electro- photocatalysis. Optimization catalysts is crucial to realize their future application devices or systems designed production fuels from sunl...

A series of dinuclear Pt(II) complexes of the type [Pt2(N,N,N',N'-tetrakis(2-pyridylmethyl)diamine(H2O)2]4+ were synthesized. Acid-base titrations, and concentration and temperature dependent stopped-flow measurements of the reaction with chloride were performed to study the thermodynamic and kinetic behaviour of the dinuclear bridged complexes. The results indicate that there is a clear intera...

eethylene polymerization catalysts became available in an enormous variety. the challenge in this research is to find catalysts that are able to connect ethylene molecules in such a way that not only linear chains are produced but variations like branched materials that possess very interesting mechanical properties like linear low density polyethylene (lldpe). in this contribution, three diffe...

A modification of the previously developed synthetic approach towards dinuclear flexibly linked salphen complexes is successfully utilized for the preparation of heterodinuclear salphen dimers. A dinuclear salphen species with Pd(II) and Cr(III) centers bears a stronger structural resemblance to the related bis-Cr(III) compound than the corresponding mononuclear Cr(III) salphen complex. Therefo...

Series of chiral palladium(II) allyl and cinnamyl complexes bearing a C1-symmetric N-heterocyclic carbenes were synthesized from achiral precursors. The chirality theses results the formation carbene-palladium bond which restricts rotation dissymmetric N-aryl substituents NHC thus creates an axis chirality. Chiral HPLC at preparative scale enabled resolution racemic provided straightforward acc...

In the polymeric title compound, {[Mn(2)(SO(4))(2)(C(30)H(36)N(6))(H(2)O)(2)]·6H(2)O}(n), the two Mn(2+) ions are bridged by two sulfate anions to form dinuclear complexes, and these dinuclear species are linked by the hexa-dentate ligand N,N,N',N'-tetra-kis(2-pyridylmeth-yl)hexane-1,6-diamine (tphn), forming a one-dimensional chain structure running in the [101] direction. The repeat unit of t...

Water-soluble dinuclear Ru-arene complexes were synthesized and found to exert promising cytotoxic effects in human cancer cells, which could be increased to an IC50 of 0.29 μM by increasing the spacer length between the metal centers. Cytotoxicity could be correlated with lipophilicity (log P Values) and water solubility. The most potent dinuclear compound, 1,12bis{chlorido[3-(oxo-κO)-2-methyl...

We herein showcase the ability of NHC-coordinated dinuclear NiI -NiI complexes to override fundamental reactivity limits of mononuclear (NHC)Ni0 catalysts in cross-couplings. This is demonstrated with the development of a chemoselective trifluoromethylselenolation of aryl iodides catalyzed by a NiI dimer. A novel SeCF3 -bridged NiI dimer was isolated and shown to selectively react with Ar-I bon...
