Second‐Generation Crystalline Sponges Enabling Consistent Structure Analysis Under Standardized Conditions for Diverse Molecules

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.

Planar Chirality Controls Diastereotopicity in [2.2]Paracyclophanyl Cyclopropenes

Chemistry – A European Journal, Volume 32, Issue 16, 25 April 2026.
In this work, we report the synthesis of [2.2]paracyclophane‐substituted cyclopropenes via rhodium‐catalyzed cyclopropenation using a pCp‐derived carbene precursor. The planar chiral framework induces diastereotopic differentiation of otherwise equivalent alkyl substituents, which is reflected in their 1H NMR spectra.

Transfer Hydrogenation of Organic Azides to Amines by Ammonia Borane Complex Under Mild Conditions Catalyzed by Reusable Au Nanoparticles

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
Organic azides are readily reduced to amines under mild conditions by ammonia borane complex, catalyzed by a low loading level of reusable Au nanoparticles supported on TiO2. We present the first protocol for the chemoselective reduction of organic azides to amines by ammonia borane complex. In the presence of a low catalytic amount of Au nanoparticles
