M.Sc. David Hoffmann (Universität Bonn): Novel synthetic routes for multiple bond formation between Si, Ge and Sn and the d- and p-block elements

AC Kolloquium
Referent/in: M.Sc. David Hoffmann
Inhalt:

For more than 150 years, unsaturated carbon containing compounds, like alkenes or alkynes, are ubiquitous building blocks in organic chemistry. Their electronic structure has been studied intensively and is nowadays well understood. In contrast, the synthesis of molecules with heavier elements of group 14 (Si-Pb) in nonsaturated bonding modes dawned in the 1970st and is still a challenging task of modern chemistry. lt demanded the development of not merely novel synthetic a pproaches and precursors but also tailored, sterically demanding substituents to protect these highly reactive functionalities. Nevertheless, the study of such compound classes and their unusual bonding motifs challenge the existing theories on chemical bonding, thus advancing our understanding of chemistry itself.
In this context, the presentation will focus on novel synthetic routes to unprecedented compounds with unsaturated heavier tetrel elements, like the heavier niobium tetrelylidyne complexes, 1,2-bromohydridogermenes, and heteronuclear alkyne analogue.
