π‐Radical Cascades to Peri‐Fused Triangulene Dimers

Angewandte Chemie, EarlyView.
We demonstrate the potential of open‐shell molecular graphene fragments as synthons for constructing graphene nanostructures via π‐radical cascades. By identifying monoradical intermediates as key selectivity‐determining species and tuning steric effects in a triangulene precursor, we show that reactivity in a formally diradical system can be ...

1,7‐Digallatetracarborane: Between Nucleophilic closo‐Cluster and “Inverse Sandwich” Digallylene

Angewandte Chemie, EarlyView.
A dianionic π‐ligand is used to make a Janus‐type twofold complex with low‐valent gallium Ga(+I). The resulting compound can be seen as and reveals the reactivity of both: a Wade‐type closo‐carborane cluster with nucleophilic Ga‐sites, as well as π‐ligand stabilized Ga(I) atoms in an inverse sandwich compound.

Excited‐State Antiaromaticity in Nonbenzenoid Aromatics: Examining the Dynamics of Intramolecular Proton Transfer With a Small Driving Force

Angewandte Chemie, EarlyView.
The excited‐state antiaromaticity of hydroxybenzotropyliums (HBTs) can be tuned through substituent effects to bring the aromatic ‘enol’ (E) and keto (K) tautomers close in energy. This leads to abnormally slow excited‐state proton transfer (on the ns timescale), giving rise to dual fluorescence emission and weak photoacidity.
