A Proposed Complete‐Cycle Mechanism for Conversion of N2 to NH3 by Mo‐Nitrogenase

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
How does the enzyme nitrogenase convert N2 to NH3 under ambient conditions? Here I describe a proposed complete cycle of the chemical mechanism, with computed energy profiles and kinetic barriers for a sequence of 31 reaction steps, encompassing 40 intermediates. How does the enzyme nitrogenase convert N2 to NH3 under ambient conditions?

Direct NMR Evidence of Distinct Cation‐CO2 Adducts in Asymmetric Phosphonium‐Based Aprotic N‐Heterocyclic Anion (AHA) Ionic Liquids

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
An in situ NMR method using isotopically enriched 13CO2 reveals regioisomeric cation‐CO2 adducts in asymmetric phosphonium‐based aprotic N‐heterocyclic anion ionic liquids. Two distinct carboxylate species, formed at chemically nonequivalent α‐carbons, are unambiguously identified and quantified.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

European Journal of Organic Chemistry, Volume 29, Issue 28, 25 July 2026.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.
