Pt/C‐Catalyzed Deuteration of Polycyclic Aromatic Hydrocarbons with Suppressed Arene Hydrogenation

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
An additive‐enabled Pt/C protocol promotes hydrogen–deuterium exchange in fused polycyclic aromatic hydrocarbons (PAHs) in D2O/2‐PrOH at 80 °C. Decalin suppresses undesired ring hydrogenation while accelerating on‐ring H–D exchange, furnishing highly deuterated PAHs (PAHs‐dn).

Synthesis of Aromatic Aldehydes by CH Formylation of Aromatics with Silyl Formates Prepared from CO2 and Hydrosilanes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
A new method has been developed for the C–H formylation of aromatic compounds using silyl formates synthesized from CO2 and hydrosilanes. This is the first report on the direct C–H formylation of aromatics with silyl formates. The formylation reactions were promoted by BBr3 or BCl3. The reaction mechanism has been clarified by DFT calculations. Despite

Programming Palladium Cage Geometry through Ligand Redox Modulation

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
A neutral redox‐active exTTF ligand (L) forms a Pd2L4 cage, whereas its oxidized form (Lox) yields a Pd2(Lox)2 macrocycle. Lox further assembles with a dibenzothiophene derivative (L′) into Pd2(Lox)(L′)2 and Pd4(Lox)4(L′)4 architectures. Reduction of Pd2(Lox)2 and Pd2(Lox)(L′)2 restores the parent Pd2L4 cage, enabling redox controlled nuclearity ...

Redox‐Active Guanidines

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

Spiro‑Linked Double Tetraphenylethenes: Solid‐State Emission and Circularly Polarized Luminescence Imaging

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...
