Activation of Aryl Halides by Triplet–Triplet Annihilation Upconversion Enabling Coupling Processes Under an Open‐to‐Air Environment

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Triplet–triplet annihilation upconversion (TTA‐UC) performed inside supramolecular viscoelastic gels enables efficient CC and C–heteroatom coupling reactions under green LED irradiation in open‐air conditions. The gel network restricts oxygen diffusion, preserves triplet states, and allows aryl halide activation through upconverted excited states ...

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

Singlet oxygen reactivity in water-rich solvent mixtures

open access: yesQuímica Nova, 2008
The 3-methylindole (3MI) oxygenation sensitized by psoralen (PSO) has been investigated in 100%, 20% and 5% O2-saturated water/dioxane (H2O/Dx) mixtures. The lowering of the ¹O2* chemical rate when water (k chem∆3MI = 1.4 × 109 M-1 s-1) is replaced

Regulation of 3‐methylindole metabolism by nuclear receptors

open access: yesThe FASEB Journal, 2012
Regulation of 3‐methylindole metabolism by nuclear receptors 3‐methylindole (3MI) is a known pneumotoxin that is found in naturally in fecal matter and is a major component of tobacco smoke; it is also a major component of boar taint, the accumulation of malodorous compounds in pigs that negatively impacts meat quality.

Reaction Pathways in the (De)hydrogenation of N‐Heterocyclic Liquid Hydrogen Carriers Over Supported Pd Catalysts

open access: yesChemSusChem, Volume 19, Issue 10, 27 May 2026.
Indoles are promising N‐heterocyclic liquid organic hydrogen carriers. Here, we investigate the reaction pathways of (methyl)indole (de)hydrogenation over Pd catalysts using reaction experiments and computational modeling: we show that distinct intermediates are formed in hydrogenation versus dehydrogenation steps, and stereocenter evolution is ...

Formation Mechanisms of Odor Substances in Mutton and Deodorization Methods: A Review [PDF]

open access: yesShipin Kexue
Mutton is a high-quality meat with high nutritional value. However, the typical species-specific flavor (odor) of mutton affects its quality and limits its consumer acceptance.

Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

open access: yesAngewandte Chemie, Volume 138, Issue 21, 18 May 2026.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of
