Flow Synthesis of Muscone‐Macrocycles Using the Eschenmoser Rearrangement as a Key Step

Helvetica Chimica Acta, Volume 109, Issue 9, September 2026.
A two‐step flow process, comprising the formation of hydrazones followed by Eschenmoser fragmentation, enables the efficient synthesis of macrocyclic ketones, which serve as precursors for exaltone and muscone. ABSTRACT Hydrazone formation followed by Eschenmoser fragmentation are key steps in the synthesis of muscone‐type macrocycles.

A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, Volume 29, Issue 5, Page 759-771, September 2026.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

Dynamic Ionic Crosslinking of Epoxidized Natural Rubber for Rebonding and Reprocessable Carbon Black–Reinforced SBR/BR Composites

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
Dynamic ionic crosslinking of ENR enables rebonding and reprocessing in carbon black–reinforced SBR/BR composites while retaining mechanical integrity. The hybrid rubber network promotes interfacial recovery, improved healing efficiency, and structural recyclability, offering a promising route toward durable and more sustainable tire‐related elastomer ...

Pure Gaussian Apodisation Reduces Integral Crosstalk Sensitivity in Quantitative NMR

Magnetic Resonance in Chemistry, Volume 64, Issue 9, Page 748-757, September 2026.
Exponential apodisation redistributes peak area away from its centre, which increases crosstalk with neighbouring peaks and reduces integral trueness when integrating between defined regions. A pure Gaussian apodisation limits wing growth: Crosstalk between peaks is not worsened, and trueness is conserved during integration.
