Immobilized CuCl2/TiO2 photocatalysts for the selective oxidation of benzyl alcohol to benzaldehyde

Photochemistry and Photobiology, EarlyView.
The photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde was investigated using free and alginate‐immobilized CuCl2 and/or TiO2 (P25) catalysts under UV irradiation. Immobilization enabled catalyst recovery and maintained high benzaldehyde selectivity but led to reduced activity due to internal oxygen diffusion limitations, which were ...

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

From Heterocubane Units to Extended Networks: Synthesis, Structure, and Optical Properties of Pb9O2I8(CN2)3 and Pb16O5I14(CN2)4

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 5, 18 March 2026.
Two air‐stable, photoluminescent lead oxide iodide carbodiimides, Pb9O2I8(CN2)3 and Pb16O5I14(CN2)4, were synthesized via solid‐state methods and structurally characterized, revealing heterocubane‐type units interconnected by iodide and (NCN)2‐ ligands.

Pyridine Into Pyrrole Transformation Induced Within the Confinement of the Macrocycle

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
This work demonstrates the nontrivial reactivity of pyridine incorporated into a porphyrin framework. The most significant achievement is the contraction of the six‐membered ring to a pyrrole ring, which is a phenomenon of great interest to researchers in this field.
