Monomer‐Dependent Selectivity in Sulfur‐Containing Ring‐Opening Copolymerisation: Bimetallic Catalysis for Predictive Design of Degradable Polymers

Angewandte Chemie, Volume 137, Issue 42, October 13, 2025.
A unified Cr(III)/Rb(I) catalyst was developed for sulfur‐based ring‐opening copolymerisation (ROCOP), enabling high selectivity. Perfectly alternating copolymers were obtained from COS with minimal byproducts. PhNCS was identified as a practical alternative. Lower selectivity and O/S scrambling were observed for CS2 and thioanhydride . Abstract Sulfur‐

Crucial Role of Oxidation for the Prebiotic Peptide Elongation Promoted by Carbonyl Sulfide

European Journal of Organic Chemistry, Volume 29, Issue 1, January 12, 2026.
The prebiotic activation of amino acid (AA) into peptides via N‐carboxyanhydride (NCA), promoted by carbonyl sulfide (COS), cannot proceed without an oxidizing step (enabling better leaving groups than sulfur dianion). While being efficient even at mild pH the prebiotic scope of COS promoted activation of AA, it is however limited because side ...

Multistep Solid-State Organic Synthesis of Carbamate-Linked Covalent Organic Frameworks. [PDF]

, 2019
Herein, we demonstrate the first example of a multistep solid-state organic synthesis, in which a new imine-linked two-dimensional covalent organic framework (COF-170, 1) was transformed through three consecutive postsynthetic modifications into porous ...

Associations of Specific Pesticides and Incident Rheumatoid Arthritis Among Female Spouses in the Agricultural Health Study

Arthritis &Rheumatology, Volume 78, Issue 1, Page 49-58, January 2026.
Objectives Growing evidence suggests farming and agricultural pesticide use may be associated with rheumatoid arthritis (RA), but few studies have examined specific pesticides and RA among women living on farms, who may personally use pesticides or may be indirectly exposed.

Application of Raman Spectroscopy Coupled With Chemometrics for the Detection and Quantification of Mancozeb Residues in Collard Green

Analytical Science Advances, Volume 6, Issue 2, December 2025.
ABSTRACT The presence of pesticide residues in food crops poses serious health concerns, necessitating precise, rapid and accessible detection techniques. This study investigates the use of Raman spectroscopy combined with advanced data analysis techniques to detect and quantify Mancozeb residues in collard greens. The primary objective was to evaluate

Pertinence d'une sélection des pesticides à mesurer dans un réseau de surveillance de la qualité des eaux superficielles à l'aide d'une méthode simplifiée d'évaluation des risques [PDF]

, 2000
L'une des difficultés rencontrées couramment dans la conception des réseaux de mesure - au moins en ce qui concerne les micropolluants - porte sur la sélection des paramètres à mesurer. C'est notamment le cas pour les pesticides, dont plusieurs centaines

Deuteration of Six‐Membered N‐Heteroarenes: Chemistry and Applications

Chemistry – A European Journal, Volume 31, Issue 67, December 1, 2025.
Deuterated six‐membered N‐Heteroarenes (6NHetAr) are finding utility in an increasing repertoire of applications. Our paper comprehensively reviews synthetic approaches that have been reported for the deuteration of 6NHetAr and their fused counterparts while providing an overview of established and emerging applications for these materials.
