AC Kolloquium - Dr. Felicitas Lips Reactivity of Amido-Substituted Silicon Ring and Cluster Compounds In my talk different synthetic pathways to unsaturated amido-substituted silicon ring and cluster compounds will be introduced. The silicon clusters feature unsubstituted atoms that we want to exploit for activation of strong bonds in small molecules such as NH3, BH3, CO2, H2, MeOH and alkenes and alkynes. By modifications of the steric and electronic properties of the amido substituent we can access different silicon ring clusters compounds with diverse electronic properties. For instance, we recently reported on a six-vertex silicon cluster with zwitterionic character that represents an unexpected isomer of hexasilabenzene. This cluster reacts with MeI and I2 and coordination of a carbene and BH3 is possible. https://www.chemie.uni-bonn.de/lu/de/lu-events/ac-kolloquium-vertretungsprofessorin-dr-felicitas-lips-1 https://www.chemie.uni-bonn.de/lu/++resource++plone-logo.svg
