Unified Synthesis of Unconventional α‐Polyhalogenated Amines Through Hydroaminoalkylation

open access: yesAngewandte Chemie International Edition, EarlyView.
A unified, redox‐neutral method that transforms alkenes and alkynes into α‐polyhalomethyl amines using stable hemiaminal reagents is reported. This approach enables access to CF3, CF2H, CF2Cl, and CFClH motifs, expanding halogenated amine space with broad substrate scope, functional group tolerance, and applicability to late‐stage modification of drug ...

Molecular Dioxygen‐Mediated Passivation of Electron Traps in n‐Type Organic Charge‐Transfer Complexes

open access: yesAngewandte Chemie International Edition, EarlyView.
O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes

open access: yesAngewandte Chemie International Edition, EarlyView.
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...
