Reducing the irreducible: using ligands with electron storage capability

Date: Tuesday, 17 November
Time: 12:00 PM
Venue: LAW G23
Speaker: Prof. Sandro Gambarotta
Department of Chemistry University of Ottawa CANADA

Abstract

Ligands capable of accepting spin density from the metal allow for the preparation of entire classes of complexes where the metal deceivingly appears in a low oxidation state. These species are in fact more correctly regarded as containing higher valent metals coupled to radical anions. Remarkably, these species retain the high reactivity that could be expected for genuine low-valent complexes, in turn providing new possibilities and tools for molecular activation. In this presentation, the use of a few of these ligands for the preparation of reduced complexes of uranium and thorium will be discussed along with a preliminary account of their chemical behaviour.
