Dual Circularly Polarized Luminescence from Chiral Boron‐Embedded Polycyclic Aromatic Hydrocarbons

Angewandte Chemie, EarlyView.
Boron‐embedded polycyclic aromatic hydrocarbons featuring an asymmetric boron center coordinated by a proximal P═O group were synthesized. Anthracene‐fused boracyclic derivatives show dual circularly polarized luminescence (CPL) arising from excited‐state P═O⋯B dissociation, which converts point chirality into C−B axial chirality.

Stereodivergent Synthesis of Three Contiguous Stereogenic Centers by Cu/Ir‐Catalyzed Borylallylation

Angewandte Chemie, EarlyView.
An alkene borylallylation strategy enabled by cooperative Cu/Ir‐catalysis has been uncovered for accessing three contiguous stereogenic centres. This strategy is notable given the inherent challenges of constructing molecules with multiple stereocenters while maintaining high selectivity bearing diverse functional groups.

Intermolekulare, Enantioselektive Nickel‐Katalysierte Arylierung von Nicht‐Aktivierten C(sp3)–H Bindungen

Angewandte Chemie, EarlyView.
Ni: neue Lösung für asymmetrische C(sp3)‐H‐Aktivierung. Die stereoselektive Synthese vollständig kohlenstoffsubstituierter quartärer Stereozentren gelingt durch eine enantioselektive C(sp3)‐H‐Arylierung unter Verwendung eines Ni‐Katalysators auf der Basis eines BINOL‐Derivaten.

Temperature‐Responsive Near‐Infrared Emission Enabled by Reversible π‐Umpolung with an Alkenyl‐Strapped Diarylboryl Unit

Angewandte Chemie, EarlyView.
Coordination of a Lewis base switches an electron‐accepting tricoordinate boron center into an electron‐donating tetracoordinate one. An alkenyl‐strapped diphenylthienylboryl π‐system undergoes phosphine‐induced reversible π‐umpolung, where transformation from an acceptor–acceptor–acceptor framework to a donor–acceptor–donor system gives rise to ...
