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

Angewandte 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.

Borane‐Catalyzed Water Dehydrogenation at Dioxaphospholes and ‐Phospholanes

Angewandte Chemie International Edition, EarlyView.
The borane‐catalyzed dehydrogenation of phenylphosphinate esters, which are formed from the reaction of dioxaphospholes and ‐phospholanes with water or air moisture under mild conditions, is reported. The mechanism of this transformation was investigated by kinetic measurements and DFT calculations, which indicate hydrogen elimination from a ...

On‐Surface Friedel–Crafts Alkylation Through a Stabilized Intermediate Complex

Angewandte Chemie International Edition, EarlyView.
On‐surface Friedel–Crafts alkylation is demonstrated on Ag(111) at the single‐molecule level. STM, XPS, and DFT calculations uncover the reaction mechanism and explain the stabilization of the key intermediate, providing insight into noble‐metal‐surface‐mediated Csp3${\rm C}_{sp^{3}}$─Csp2${\rm C}_{sp^{2}}$ coupling. ABSTRACT The incorporation of sp3${\
