(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications
Angewandte Chemie, EarlyView.In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation
Angewandte Chemie, EarlyView.Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...
