Sven Schneider (chemist)

Sven Schneider (* 1972 ) is a German chemist ( complex chemistry , catalysis ).

Schneider studied chemistry from 1993 at the TU Darmstadt with a diploma in 1999 under H.-F. Small. He was also studying abroad at the University of Bristol in 1995/96 . In 2003 he received his doctorate under Alexander Filippou at the Humboldt University in Berlin (dissertation: Triamidoamine complexes of chromium (II-IV) and cobalt (II) ) and received the University's Fischer-Nernst Prize. As a post-doctoral student , he was with Tobin Marks at Northwestern University until 2006 . He then worked with Wolfgang A. Herrmann at the Technical University of Munich , where he completed his habilitation in 2010 (Habilitation thesis: Small molecule activation by cooperative transition metal amido complexes: mechanistic aspects and perspectives ). In 2006 he received a Liebig grant and was accepted into the Emmy Noether Program of the DFG. In 2009 he received the sponsorship award from the Otto Röhm Memorial Foundation. From 2010 he was Professor (W2) at the Friedrich-Alexander-Universität Erlangen-Nürnberg and from 2012 Professor (W3) at the Georg-August-Universität Göttingen .

He is researching catalysts in the form of electron-rich metal complexes with cooperating ligands such as amides that activate EH bonds (where E stands for carbon, hydrogen, nitrogen or boron). Activation of HH is an important step in the hydrogenation of polar functional organic groups such as ketones. Extension to inorganic substrates such as BH is of interest for novel inorganic polymers or ammonium boranes. The latter are of interest in chemical hydrogen storage . Similar catalysts can also cause the hydrogenation of azides to ammonia (a model system for ammonia synthesis under much milder conditions than in the Haber-Bosch process ).

He and his group developed aliphatic pincer ligands of the form PNP (for phosphorus-nitrogen-phosphorus), whose electron donor properties can be easily controlled and which can serve as a reversible reservoir for protons and electrons (redox reactions).

In 2010 he received the Chemistry Prize of the Academy of Sciences in Göttingen for creative work on new catalyst systems that use the interaction of metal and ligand (laudation). In 2015 he received an ERC Consolidator Grant.
