Dihydrogen Activation by Antiaromatic Pentaarylboroles [PDF]
Journal of the American Chemical Society, 2010 Facile metal-free splitting of molecular hydrogen (H(2)) is crucial for the utilization of H(2) without the need for toxic transition-metal-based catalysts. Frustrated Lewis pairs (FLPs) are a new class of hydrogen activators wherein interactions with both a Lewis acid and a Lewis base heterolytically disrupt the hydrogen-hydrogen bond.

Stabilization of the Benzene Radical Trianion in an Inverse‐Sandwich Yttrium Complex
Angewandte Chemie, EarlyView.A new type of benzene anion state is born: The unprecedented benzene radical trianion embedded in an inverse‐sandwich yttrium complex was synthesized by a one‐electron chemical reduction of its benzene dianion precursor using potassium graphite in the presence of [2.2.2]‐cryptand.

Shaping Antiaromatic π‐Systems by Metalation: Synthesis of a Bowl‐Shaped Antiaromatic Palladium Norcorrole [PDF]
Angewandte Chemie International Edition, 2017 AbstractThe synthesis of a bowl‐shaped antiaromatic molecule was achieved through the deformation of a planar antiaromatic porphyrinic π‐conjugation system by insertion of palladium into the small cavity of a metal‐free norcorrole. The bowl‐to‐bowl inversion dynamics of the antiaromatic Pd‐coordinated norcorrole was determined by variable‐temperature ...

Competition Between Sextet Aromaticity and Cyclobutadiene Antiaromaticity within the Same Molecule: Location is Important [PDF]
, 2021 The interplay between aromaticity and antiaromaticity is maximized in [n]phenylenes. In their smaller isomer sets, some isomers can be aromatic while others can be antiaromatic.
