Abstract:
Fundamental research allows us to find new, economically and ecologically attractive ways to meet current challenges. The uncertainty of available phosphorus resources is an urgent concern. Unlike oil, which is lost once used, phosphorus can be recovered and used over and over again or at least transformed into other P-compounds of chemical use. The intention of our research is to contribute to the field of synthetic chemistry both, inorganic and organic, by identifying and developing highly-reactive phosphorus reagents that can be potentially regenerated. In particular, we are interested in Weiss-type compounds which are containing N– (12+, 23+) or C–based (32+, 43+) ligands which we call SynPhos reagents. 


 


 

We are entering new avenues of phosphorus chemistry and address fundamental questions to develop new applications which can also be extended to the heavier group 15 congeners. Using those novel and powerful SynPhos reagents, new concepts for more efficient, selective and sustainable synthetic procedures are developed. Our research also intends to develop greener and more efficient processes and, whenever possible, to recover the phosphorus after the reaction. Thus, novel phosphorus-based compounds can be used in the recovery of industrial waste by-products such as phosphane oxides and, therefore, have a positive impact on certain chemical industries and the environment.

Name: Prof. Dr. Jan J. Weigand

Organization: TU Dresden

Profile Weblink: http://www.chm.tu-dresden.de/ac3/

Jan J. Weigand obtained his diploma in chemistry in 2002 and his Dr. rer nat. in 2005 from the LMU in Munich. He was awarded in 2005 with the Bavarian culture prize and obtained a Lynen Scholarship from the AvH foundation for postdoctoral research at Dalhousie University in Halifax (Canada). He returned to Germany with a “Lynen Return Fellwopship” and started his habilitation at the WWU Münster end of 2007 under the supervision of Prof. Hahn. He was awarded shortly after with the Liebig scholarship of the FCI which allowed him in 2008 to start his independent career. In April 2010 he became fellow of the very prestigious Emmy Noether research program awarded by the DFG and obtained recently the Wöhler research award for young scientist. Very recently, in July 2012, he also obtained from the EC (European council) an “ERC starting grant” which additionally funds his research for another 5 years. Since 1.01.2013 he is Full-Professor at the TU University Dresden.  His group is interested in multiply charged and neutral main group element compounds, their reactivities in synthesis and sustainable applications and inorganic coordination chemistry. Since 1.02.2015 he is professor for inorganic molecular chemistry at the TU Dresden.
