Faculty of Chemistry

 

Welcome to the Faculty of Chemistry

In order take the sustainability and environmental compatibility into account the research foci in chemistry have changed during the last years. The enormous importance of chemistry in economy, i.e. energy supply, development of new materials, pharmaceutical research and biotechnology, is unambiguous. The close collaboration of the Faculty of Chemistry with natural scientists and engineers of the University Stuttgart, as well as with scientists of the local Max-Planck-, Fraunhofer-, and Textile Chemistry and Chemical Fibers Institute, provides a considerable location advantage.

Invited Review in Zeitschrift für Kristallographie – Crystalline Materials: On Halide Derivatives of Rare-Earth-Metal(III) Oxidomolybdates(VI) and –Tungstates(VI)

Halide derivatives of rare-earth metal(III) oxidomolybdates(VI) and –tungstates(VI) are within the focus of extended research in materials chemistry, because they do not only exhibit interesting structural details but also have proven to be suitable host materials for luminescence applications. The micro review represents a comprehensive, however incomplete overview of the results achieved by our and other groups in this area of research.

Publication in Nature Communications: A Four-Coordinate Cobalt(II) Single Ion Magnet With Coercivity and a Very High Energy Barrier

Single-molecule magnets display magnetic bistability of molecular origin, which may one day be exploited in magnetic data storage devices. Recently it was realised that increasing the magnetic moment of polynuclear molecules does not automatically lead to a substantial increase in magnetic bistability. Attention has thus increasingly focussed on ions with large magnetic anisotropies, especially lanthanides. In spite of large effective energy barriers towards relaxation of the magnetic moment, this has so far not led to a big increase in magnetic bistability. Here we present a comprehensive study of a mononuclear, tetrahedrally coordinated cobalt(II) single-molecule magnet, which has a very high effective energy barrier and displays pronounced magnetic bistability. The combined experimental-theoretical approach enables an in-depth understanding of the origin of these favourable properties, which are shown to arise from a strong ligand field in combination with axial distortion. Our findings allow formulation of clear design principles for improved materials.

VIP Publication in Angewandte Chemie, Int. Edition: Bismuth Undecahydro-closo-Dodecaborane: A Retainable Intermediate of B–H-Bond Activation by Bismuth(III) Cations

The icosahedral [B12H12]2– anion manifests an amazingly high stability against metal cations in aqueous solution, but for a long time interactions of this soft anion with soft cations via non-classical hydrogen bonds are known. The now presented hydrogen abstraction at the [B12H12]2– cluster by bismuth(III) cations leading to molecular BiB12H11 (shown as electroneutral pentahydrate in the figure) reveals a hitherto unknown and surprising reactivity of this anion.

Publication in Angew. Chem. Int. Ed.: Diastereodivergency enabled by a novel polyfunctional cooperative catalyst concept

Diastereodivergency is one of the major current challenges for catalytic asymmetric synthesis, because very often the production of one diastereomer is strongly inherently preferred, while other diastereomers are not directly accessible as major products. Overwriting this inherent preference by a suitable catalyst necessitates the control over the spatial arrangements of both reaction partners in the diastereoselectivity determining transition state. We have reported a new polyfunctional catalyst concept in which a Lewis acid, H-bond donors and a chiral bisazolium core cooperate in the stereocontrol of the direct 1,4-addition of oxindoles to nitroolefins. Both possible product epimers are thus for the first time accessible as major products on demand by changes to the ligand constitution and configuration providing novel synthetic means e.g. for alkaloid syntheses.

Publication in Angew. Chem. Int. Ed.: Development of the most efficient Pd catalyst towards enantiopure benzylic amines by 1,2-additions

Enantiopure benzylic amines play an important role for the development of new medicines. We have shown that a readily accessible planar-chiral palladacycle is a highly efficient catalyst for the formation of this compound class accelerating the 1,2-addition of arylboroxines to both aromatic and aliphatic imines with extraordinary levels of enantioselectivity. Using aldimines an additional base was not required for the boroxine activation using acetate as an anionic ligand. Problems frequently observed for other Pd catalysts like aryl–aryl homocouplings or imine hydrolysis were fully overcome (even in the absence of molecular sieves).

Publication in Angew. Chem. Int. Ed.: Catalytic Asymmetric C-Alkylation of Pharmacologically Important Isoxazolinones

Isoxazolinones are important heterocycles for the development of news medicines. These cyclic oxime esters are also valuable synthetic building blocks containing various functional handles. We have reported the first catalytic asymmetric alkylations of isoxazolinones forming all-C-substituted quaternary stereocenters. This investigation of a direct 1,4-addition identified a palladacycle complex as very efficient catalyst allowing for high enantioselectivities, regioselectivities and remarkable turnover numbers of up to 1900.
