Universität Stuttgart - "Making Use of Anti-Aromatic Destabilization: Boroles in Main Group Chemistry”⠀

Our group is interested in the synthesis of new boracyclopentadienes (or boroles) and making use of its unique cyclic 4-π-electron system. The (weak) anti-aromatic destabilization intrinsic to these molecules provides them with exceptional reactivity (including major rearrangements) to overcome the anti-aromaticity.
We investigate 2,5-disilyl substituted boroles and this contribution will detail how this substitution pattern enables further chemistry particularly with regards to silyl migrations induced by reactions with nucleophilic silylenes. Among a variety of further examples, a new access route to nido- and arachno-type silacarborane clusters, boryl-substituted silylium ylides and a borole-backbone based donor-supported silavinylidene will be presented.
