Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Methane Activation by B5+ Toward a CB5H2+ Isomer Containing a Planar Tetracoordinate Carbon Atom

Angewandte Chemie, EarlyView.
Methane activation by B5+ yields CB5H2+ through H2 elimination. Electronic‐structure calculations connect the nascent dehydrogenation product to a low‐lying isomer containing a planar tetracoordinate carbon atom. ABSTRACT Planar tetracoordinate carbon (ptC) motifs have been identified predominantly in the global‐minimum structures of gas‐phase clusters

Chiral Fjord‐Edged Nanographenes Constructed by Allylic‐Migration‐Mediated Cyclization

Angewandte Chemie, EarlyView.
A novel allylic‐migration‐mediated cyclization strategy enables the construction of two fjord‐edged nanographenes without steric blocking groups. The resulting non‐planar molecules exhibit remarkable chiroptical properties, with an absorption dissymmetry factor surpassing those of pristine [5]helicene and previously reported fjord‐edged nanographenes ...

Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes

Angewandte Chemie, EarlyView.
Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are
