Revisiting CN− Formation Mechanisms in Electron Collisions with Benzonitrile

ChemPhysChem, EarlyView.
This study explores negative ion formation via electron attachment, revealing CN− formation at 3.0 and 7–10 eV. Dissociation pathways are analyzed using G4(MP2) and CASPT2 calculations, highlighting the coupling between the π4* and σ* resonances critical for interstellar chemistry. Radiation‐induced processes in the aromatic cyano compound benzonitrile

Probing the Hybrid σ/π‐Holes in sp2‐Hybridized Chalcogen Bond Donors and their Complexes with Ammonia

ChemPhysChem, EarlyView.
A double‐bonded chalcogen bond donor exhibits both a σ‐hole and a π‐hole on the same atom. These unique σ/π‐holes can be tuned based on molecular composition to be directional or semidirectional depending on the donor–acceptor bonding configuration, which differs from the behavior of other electropositive holes.

Spontaneous Mirror‐Symmetry Breaking Destabilizes Racemates: A Route to Homochirality and Reversed Chemical Selectivity

ChemPhysChem, EarlyView.
Reaction networks yielding spontaneous mirror‐symmetry breaking (SMSB) are revisited. All include a first‐order enantioselective autocatalysis, which, on its own, is unable to lead to SMSB. The coupling with the so‐called ancillary reactions (racemization, mutual inhibition, etc.) makes the racemic state unstable.
