Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Frame‐Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Modern chemistry seeks to turn the simple raw materials into complex molecules that matter in health, agriculture, and technology. Among these, oligoheterocycles stand out for their versatility, yet they are most often built by cross‐coupling reactions that often rely on expensive metal catalysts.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Bifunctional Aziridines from Photochemically Generated FSO2NH2 for SuFEx Diversification of Alkenes

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Photochemically generated FSO2NH2 serves as a safe, practical nitrene precursor for Rh‐catalyzed aziridination of alkenes, granting access to previously inaccessible fluorosulfonyl aziridines. These bifunctional electrophiles merge aziridine ring strain with SuFEx reactivity to provide a modular platform toward aliphatic sulfamoyl fluoride derivatives ...

Coordination Studies of a Triazole‐Substituted 3H‐1,2,4‐Diazaphosphole: CC and CN Bond Activation Induced by Cobalt(0) and Nickel(0) Complexes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Reactions of a triazole‐substituted 3H‐1,2,4‐diazaphosphole with electron‐rich cobalt and nickel complexes result in the selective cleavage of CC and CN bonds on the triazole, forming chelate complexes with the activated diazaphosphole ligand. The reactivity of the recently reported 3H‐1,2,4‐diazaphosphole 1 toward electron‐rich Ni and Co complexes ...
