| Speaker | Professor Katalin Barta (Professor at the Faculty of Science and Engineering, Synthetic Organic Chemistry, Stratingh Institute for Chemistry, University of Groningen, Netherland). Katalin started her independent career at the Stratingh Institute for chemistry at the University of Groningen in 2013 where she was promoted to Associate Professor in 2017. She obtained her Master’s degree in chemistry from ELTE Budapest (Hungary). Her master’s research was in the area of alternative solvents and fluorous biphase chemistry under the supervision of Istvan T Horvath. Then she completed her PhD (2008) under the supervision of Walter Leitner in asymmetric catalysis and ligand design at RWTH-Aachen, Germany. After, she carried out postdoctoral research (2008-2010) with Peter Ford at University of California, Santa Barbara and subsequently worked as Associate Research Scientist (2010-2012) at Yale University, the Center for Green Chemistry and Engineering (New Haven, USA) with P. T. Anastas. Her post-doctoral work focused mainly on the catalysis and renewable resources, including lignin valorisation. Combining various fields, the research interests in the Barta group are broadly in Sustainable and Green Chemistry, focusing on the development of novel homogeneous and heterogeneous catalytic strategies for the conversion of all main components of lignocellulose, utilizing Earth-abundant metals. Katalin is recipient of the ERC starting grant 2015, and the VIDI award of the NWO. She is funding member and secretary of the EuChemSoc division Green and Sustainable chemistry and member of the YAE (Young Academy of Europe). |

Abstract: In order to achieve true economic feasibility of future biorefineries, it should be ensured that maximum value is derived from all individual components of lignocellulose.[1] Especially the catalytic conversion of the lignin component to well defined aromatic compounds has proven challenging.[2] Furthermore, the downstream processing of the platform chemicals obtained from cellulose(s) and lignin still needs significant improvement in order to access sufficient diversity of products, ultimately covering an entire value pyramid of new bio-based materials.
Importantly, research questions need to be re-designed to maximize material balance, energy efficiency and sustainability in the new catalytic pathways and globally.
In this lecture I will describe our “cleave and couple” strategy, where “cleave” refers to the catalytic deconstruction of lignocellulose[2] or lignin[3,4] to aromatic and aliphatic alcohol intermediates, and “couple” involves the development of new transformations for the formation of C-C and C-N bonds[2,5,6] in order to obtain a range of products from lignocellulose.
