Polarity of liquid mixtures with components of limited miscibility [PDF]

open access: yes, 1986
Binary mixtures of organic solvents with limited miscibility are investigated by a two parameter equation which reliably describes the polarity of mixtures as a function of their composition.

Sorption of Sulfonamide Antibiotics in Peat Soils With Different Properties

open access: yesJournal of Plant Nutrition and Soil Science, Volume 188, Issue 3, Page 482-494, June 2025.
Sulfonamide antibiotics contaminate peat soils where they are sorbed to functional groups in a pH‐dependent manner that can be successfully described by QSAR. ABSTRACT Background Sulfonamide antibiotics have been discovered as emerging pharmaceutical pollutants worldwide and are only poorly removed in wastewater treatment.

Discovery and In Vitro Reconstitution of Closoxazole Biosynthesis from Pyxidicoccus fallax

open access: yesChemBioChem, Volume 26, Issue 10, May 27, 2025.
The myxobacterium Pyxidicoccus fallax is found to be a producer of benzoxazole‐containing natural products named closoxazoles. In vitro studies with the biosynthetic enzymes reveal new insights into the reaction mechanism for closoxazole formation.

Photocarboxylation of Arylated 2H‐Azirines Exploiting Continuous Flow Technology

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 18, May 23, 2025.
An efficient continuous process for the synthesis of trisubstituted oxazoles is reported which links the photochemical opening of azirines and the subsequent trapping of the azomethine ylides with CO2 gas. This highlights challenges and solutions when incorporating CO2 as a feedstock material for the photochemical synthesis of small heterocyclic ...
