Synthesis of Polysubstituted Tetrahydro‐1,4‐Thiazepines by Rhodium‐Catalyzed Ring Expansion of Dihydro‐1,3‐Thiazines with Diazoesters

Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.
A rhodium(II)‐catalyzed ring expansion of stereodefined dihydro‐1,3‐thiazines with diazomalonates gives 1,4‐thiazepines via a sulfonium ylide rearrangement. The reaction shows a cis/trans reactivity divergence arising from different metal coordination, as revealed by experiments and density functional theory studies.

Quartzite Waste–Based Composite: An Environmental and Renewable Material for the Adsorptive Removal of Industrial Dyes

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
A carbon‐supported quartzite powder waste composite was evaluated as a sustainable and low‐cost adsorbent for the removal of the cationic dye Methylene Blue (MB) and the anionic dye Reactive Black 5 (RB5). The valorization of quartzite waste as a silica source represents an environmentally attractive strategy to mitigate disposal impacts while enabling
