Low-valent 1st row Transition Metals: Catalytic Activity and Unusual Magnetic Behaviour, with Dr Emma Richards, University of Cardiff
Date: 25 January 2019 Time: 12:30 - 13:30
Dr Emma Richards from the University of Cardiff will be giving a seminar entitled “Low-valent 1st row Transition Metals: Catalytic Activity and Unusual Magnetic Behaviour”.
Abstract: Electron paramagnetic resonance (EPR) spectroscopy is an extremely versatile technique for the characterisation of homogeneous catalysts involving paramagnetic centres. The paramagnetic parent pre-catalyst, the activated catalyst itself or any resulting reactive intermediates, can all be monitored in situ in order to delineate the role of the formal metal oxidation state and the influence of ligand structure on the resulting catalytic activity. This seminar will detail how highly reactive, low valent transition metal complexes of formal oxidation states, focussing on Fe(I) and Ni(I), coordinated by phosphine or N-heterocyclic carbene (NHC) ligands are active for a range of cross-coupling reactions.
