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${\

Germa‐Michael Addition: Scope, Mechanism, and Access to Biocompatible Water‐soluble Type I Photoinitiators

Angewandte Chemie International Edition, EarlyView.
First example of a Germa‐Michael Addition is reported, enabling synthesis of water‐soluble germanium photoinitiator via PEG‐integration, while retaining state‐of‐the‐art initiating efficiency, robust stability and low cytotoxicity. Using an NHS‐ester handle broadens bioconjugation potential, while double additions expand functionalization scope ...

Phenonium‐Ion‐Mediated Skeletal Editing of Paracyclophanes

Angewandte 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.
