Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Synthesis and characterization of galloaluminosilicate/gallosilicalite (MFI) and their evaluation in methane dehydro-aromatization

, 2001
MFI-type gallosilicalite and galloaluminosilicate were synthesized by hydro-thermal method. For all the as-synthesized Ga-containing samples, Ga-71 MAS NMR spectra confirmed that the Ga3+ cations are located in the zeolite framework.

Amine‐Triggered Azabenz‐Annulation of Cyclic Secondary Amine‐Functionalized Perylene Diimides for Dual‐Mode Sensing

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Pictet‐Spengler Intermediate of a cyclic secondary amine perylene diimide undergoing amine‐triggered conversion to azabenz‐annulated perylene diimide, inducing a high‐contrast green‐to‐yellow color change along with fluorescence turn‐on, demonstrating intuitive “safe” to “warning” dual‐mode sensing.

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.
