Salt Cluster With Surface Defect Shows Anomalous Acid–Base Chemistry

Angewandte Chemie International Edition, EarlyView.
The acid displacement of formic acid in sea‐salt aerosols, releasing HCl, challenges conventional acid–base chemistry. Our gas‐phase experiments show that this reaction occurs on pure NaCl cluster ions in the absence of water. Surface defects of the NaCl cluster ions enable this reaction via enhanced electrostatic interactions of the salt ions with the

Sustainable Ammonia Electrosynthesis Coupled With Glycerol Valorization via an Adaptive Tri‐Component Catalyst

Angewandte Chemie International Edition, EarlyView.
A Cu‐Ni‐W tri‐component catalyst enables efficient nitrate‐to‐ammonia conversion under pulsed electrolysis. Combined experimental and theoretical studies attribute its performance to component synergism and regulated intermediates. Its facile adaptation for glycerol valorization to formic acid underscores a versatile system design concept, advancing ...

Intermolecular Enantioselective Nickel‐Catalyzed Arylation of Un‐Activated C(sp3)─H Bond

Angewandte Chemie International Edition, EarlyView.
Ni: a new solution for asymmetric C(sp3)─H activation. The stereoselective synthesis of all‐carbon quaternary stereogenic centres is achieved via enantioselective C(sp3)─H arylation using a Ni‐BINOL‐derived catalyst. Rational catalytic cycle design uncovers a new reaction pathway that can efficiently induce chiral information during the stereoselective

Structural Revision of the C16 Sesquiterpene Hegelenether and the Mechanism of C6‐Methylation in Terpene Biosynthesis

Angewandte Chemie International Edition, EarlyView.
The structure of the non‐canonical C16 sesquiterpene named hegelenether was revised to the structure of marxdiol, and its absolute configuration was assigned. Isotopic labeling experiments revealed the stereochemical course of the methyltransferase involved in its biosynthesis.
