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

Complementary Eigen–Zundel Interpretation Reconciles Thermodynamics and Spectroscopy of Excess Protons in Aqueous HF Solutions

open access: yesAngewandte Chemie International Edition, EarlyView.
Aqueous solutions of HF and HCl show contrasting dissociation in water, yet exhibit nearly identical excess‐proton spectra. This puzzling observation is reconciled by a complementary Eigen–Zundel interpretation. ABSTRACT Aqueous solutions of HF and HCl behave very differently at intermediate concentrations: HCl dissociates completely, whereas HFonly ...
