Cages vs. Prisms: Controlling the Formation of Metallosupramolecular Architectures with Ligand Side-Chains

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Giacomo Cecot, Andrea Luca Ramorini, Ophélie Marie Planes, Martin Tim Doll

Metallosupramolecular assemblies of the general formula M2nLn can adopt prismatic or cage‐like structures. The factors controlling the aggregation number n and the geometry of the final assembly are still not fully understood. Here, we describe the synthes ...

Rh-I, Ir-III ,and Co-III Complexes with Atropchiral Biaryl Cyclopentadienyl Ligands: Syntheses, Structures, and Catalytic Activities

Nicolai Cramer, Gints Smits, Coralie Danielle Annick Duchemin

Chiral cyclopentadienyl (Cp-x) group 9 metal complexes have become versatile catalysts for a variety of efficient enantioselective C-H functionalizations. Atropchiral binaphthyl-derived Cp-x ligands having tuning options at the 3,3'-positions present a rob ...

Molecular nanostructures based on polyfunctional clathrochelate complexes

Suzanne Maria Jansze

This thesis describes the design and synthesis of clathrochelate metalloligands for the construction of molecular nanostructures. The low synthetic effort, versatility and stability of the clathrochelate metalloligands makes them particularly suited to the ...

A ligand-based system for receptor-specific delivery of proteins

Kai Johnsson, Luc Reymond

Gene delivery using vector or viral-based methods is often limited by technical and safety barriers. A promising alternative that circumvents these shortcomings is the direct delivery of proteins into cells. Here we introduce a non-viral, ligand-mediated p ...

A complete series of uranium(iv) complexes with terminal hydrochalcogenido (EH) and chalcogenido (E) ligands E = O, S, Se, Te

Marinella Mazzanti

We here report the synthesis and characterization of a complete series of terminal hydrochalcogenido, U–EH, and chalcogenido uranium(IV) complexes, U≡E (with E = O, S, Se, Te), supported by the (Ad,MeArOH)3tacn (1,4,7-tris(3-(1-adamantyl)-5-methyl-2-hydrox ...

Nickel-Catalyzed Enantioselective Pyridone C-H Functionalizations Enabled by a Bulky N-Heterocyclic Carbene Ligand

Nicolai Cramer, Johannes Diesel, Anastasiia Finogenova

Annulated pyridones are an importantscaffold found in many biologically active compounds. ANi(0)-catalyzed C−H functionalization of 2- and 4-pyridones is disclosed, providing access to annulatedpyridones via enantioselective intramolecular olefin hydro-ary ...

Reversible disassembly of metallasupramolecular structures mediated by a metastable-state photoacid

Kay Severin, Giacomo Cecot, Suzanne Maria Jansze

The addition of a metastable-state photoacid to solutions containing metal–ligand assemblies renders the systems light responsive. Upon irradiation, proton transfer from the photoacid to the ligand is observed, resulting in disassembly of the metallasupram ...

High-pressure NMR spectroscopic and calorimetric studies on formic acid dehydrogenation and carbon dioxide hydrogenation

Cornel Fink

Our current energy production is convenient and simple, but it is not sustainable. The negative impacts on our environment are omnipresent in the form of smog, extinction of species, and global warming. A major challenge of our generation is the transition ...
