Rieske Iron–Sulfur Cluster Proteins From an Anaerobic Ammonium Oxidizer Suggest Unusual Energetics in Their Parent Rieske/Cytochrome b Complexes

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 4, Page 905-920, April 2026.
ABSTRACT Anaerobic ammonium‐oxidizing (anammox) bacteria employ a unique, hydrazine‐based pathway to obtain energy from nitrite and ammonium. These organisms possess distinct Rieske/cytochrome b complexes whose precise role in anammox metabolism remains unclear, but which have been proposed to include the generation of NAD(P)H.

Light‐Induced Reactions of Small‐Membered Cyclic Carbonyl Compounds

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
This review highlights recent advances in the synthesis and photochemical reactivity of cyclopropenone and cyclobutenedione. These compounds undergo photolysis upon direct excitation, and in some cases, through indirect excitation by photocatalysts. The resulting photogenerated species exhibit unique reactivity profiles that are strongly influenced by ...

Electrochemical Dehydration of Carboxamides to Their Nitriles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
Electrochemical dehydration of carboxamides to nitriles is achieved using thiocyanate‐mediated activation, avoiding stoichiometric reagents. In an undivided cell at ambient conditions, 18 aromatic and aliphatic substrates give good‐to‐excellent yields (up to 84%) with functional‐group tolerance. Cyclic voltammetry supports an EC‐type‐mediated oxidation.

Alpha‐Ester Aryl Diazirines: Low‐Temperature Carbene Progenitors for Materials Applications

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 5, 3 March 2026.
A synthetic route to α‐ester aryl diazirines is established. The products are shown to have low activation temperatures, and to form stabilized singlet carbenes, resulting in high‐yielding C–H insertion to unactivated aliphatic bonds. Applications in materials science and tissue adhesion are proposed.
