Abundance of atrazine degrading genes trzN versus atzA in soil cultures and in situ degradation rates

Pest Management Science, EarlyView.
Atrazine degradation in agricultural soils showed in situ half‐lives of 36–225 days. Field and laboratory results indicate active microbial hydrolysis driven mainly by trzN. Biphasic degradation sustains long‐term persistence, maintaining the potential for groundwater contamination despite reduced immediate leaching risk.

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

Smart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.

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

European 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 ...

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Heterogeneous Iodine Chemistry Impacts Reactive Halogen and Oxidant Abundances

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Tropospheric reactive halogens influence the oxidizing capacity of the atmosphere. Although previous studies have shown that iodine exerts the strongest impact on tropospheric ozone concentrations compared to chlorine and bromine, the impact of aerosol iodide recycling back to the gas phase on oxidants has not been estimated prior to this work.
