报告摘要：Professor Jan J. Weigand obtained his diploma in chemistry in 2002 and his PhD in 2005 from the LMU in Munich. He obtained the Bavarian culture prize and Lynen Scholarship at Dalhousie University in 2005, the Liebig scholarship of the FCI in 2008 to start his independent career, the fellow of the very prestigious Emmy Noether research program awarded by the DFG in 2010 and the Wöhler research award for young scientist at the same year. Since 2013 he is Professor at the TU Dresden. As well as molecular inorganic and phosphorus chemistry, his research focuses on the development of sustainable methods in extraction and technical applications including novel recycling strategies. The latter particularly includes the development and improvement of innovative catalyst systems via synthetic and post synthetic strategies for application in petrochemical industry and resource change to biogenic and fossil residues. In 2023 he received a Reinhardt Koselleck funding from the DFG for the project - Blueprint for a modern sustainable phosphorus chemistry and he is a member of the CTC-Expert Pool (Center for the Transformation of Chemistry) since 2023.
报告人简介：The current depletion of available primary phosphorus resources is extremely worrying, which is why phosphate rock and elemental phosphorus are listed as critical raw materials worldwide. The problem of phosphorus recovery through suitable large-scale recycling processes to recover valuable phosphorus compounds will become drastically more acute in the future. In Jan J. Weigand’s blueprint for a modern sustainable phosphorus chemistry, we investigate systematic and atom and energy efficient ways to either directly convert P4 via our concept of “oxidative onioation“selectively into salts of versatile P(III) transfer reagents suitable for subsequent formation of P–O, P–N and P–C bonds or the deoxygenation of phosphoric acid and recycled phosphate resources to P1 building blocks, allowing 'redox neutral' synthesis of a variety of valuable P(V) compounds. Both concepts represent versatile and chlorine-free approaches to value-added and highly relevant phosphorus containing chemicals.
