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

Engineering Polar Nanoregions in COFs via Controlled Symmetry Breaking Toward Piezocatalysis

Angewandte Chemie, EarlyView.
Polar nanoregions (PNRs) are engineered within covalent organic frameworks via asymmetric grafting of highly polar polyfluoroalkyl chains, which enables controlled symmetry breaking. These randomly oriented artificial PNRs dynamically respond to mechanical stimuli and impart relaxation behavior to the COFs (TFB‐TAPT‐FA).

Macrocyclization of ω‐Isocyano Aldehydes

Angewandte Chemie, EarlyView.
The ω‐isocyano aldehydes readily undergo cyclization to afford α‐acyloxy, α‐hydroxy, α‐acetamido, and α‐keto macrolactams, as well as tetrazole‐fused macrocycles, via C(sp3)─C(sp2) bond formation, providing access to diverse α‐functionalized medium‐sized lactams and macrolactams. ABSTRACT Medium‐sized rings and macrocycles constitute a privileged class

Bio-based, selenium/Schiff base-containing co-curing agent enables flame-retardant, smoke-suppressive and mechanically-strong epoxy resins

Epoxy resins (EPs) have excellent overall properties, but their inherent flammability severely limits their industrial applications. Most existing flame-retardant methods rely on phosphorus-based compounds.
