Gold Single‐Atom Catalysts Enable Selective Shuttle Hydrochlorination of Alkynes

open access: yesAngewandte Chemie International Edition, EarlyView.
Gold single‐atom catalysts on activated carbon enable heterogeneous shuttle hydrochlorination of terminal alkynes to vinyl chlorides with high chemo‐ and stereo‐selectivity thanks to cooperation between Au(I) sites and the support. The catalytic system combines broad substrate compatibility, simplified separation, and recoverability, paving the way for

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.
