Exploring the Ring–Ring Expansion and Pyrazole Substitution of Chlorophosphazenes [PCl2N]3,4 Through Mechanochemical Ball‐Milling and Quantum Mechanical Computation

Journal of Heterocyclic Chemistry, EarlyView.
Mechanochemical ball‐milling of cyclic chlorophosphazenes at room temperature enables ring–ring expansion to larger cycles and pyrazole substitution, avoiding hazardous solvents and high temperatures. ABSTRACT In this study, we are using low‐energy mechanochemical ball‐milling with [PCl2N]3–4 at room temperature as an alternative to high‐temperature ...

Evaluating the Impact of Phosphate‐Buffered Saline Solutions on the Micellar Behavior of Dimeric Surfactants and Their Interaction With Lipid Membranes

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT Over the past few years, dicationic alkylammonium bromide dimeric surfactants have emerged as promising agents for numerous biotechnology and medical applications. However, there have been few studies examining their behavior within a biological context, particularly regarding the impact physiological buffers have on their physico‐chemical ...

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‐
