My Research Project:

As main topic, my research project focuses on low-valent silicon compounds. These are compounds in which the present silicon atom displays less than the common fourfold binding mode. This is the case for example in molecules with Si-Si double bonds (disilenes), with silicon displaying a lone pair (silylenes, like carbenes in carbon chemistry) or with silicon radicals. The aim of this research is therefore the synthesis and characterisation of new molecular compounds containing low-valent silicon. These compounds exhibit unique reactivity properties which are mostly still unexplored. The focus here is the application for the activation of small molecules like CO2 or hydrogen and the answer to the question "is silicon able to perform catalysis?”.

Key words: low-valent silicon, small molecule activation, advanced synthesis
