Aza‐Büchner–Curtius–Schlotterbeck Reaction Enables Selective Construction of Quaternary Carbon Centers

open access: yesAngewandte Chemie International Edition, EarlyView.
We introduce the Aza‐Büchner–Curtius–Schlotterbeck (ABCS) reaction: A mild, catalyst‐free method for homologating aryl imines. Diverging from the traditional BCS mechanism, the diazo intermediate undergoes selective C─C insertion to form an all‐carbon quaternary center.

Phenonium‐Ion‐Mediated Skeletal Editing of Paracyclophanes

open access: yesAngewandte Chemie International Edition, EarlyView.
Phenonium‐ion chemistry enables the modular skeletal editing of paracyclophanes. Regioselective nucleophilic trapping expands one or both aliphatic bridges, enables iterative access to higher paracyclophane homologues, and translates bridge topology into a functional design parameter, as demonstrated with a bridge‐expanded TADF emitter.
