Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...

Sustainable Diepoxide Monomers for Polyoxazolidinone‐Based High‐Performance Thermoplastics

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
Sustainable diglycidyl ethers could replace bisphenol A diglycidyl ether (BADGE) as a building block for polyoxazolidinones, yielding high‐performance thermoplastics with similar thermal and mechanical properties. Owing to their outstanding mechanical, thermal, and chemical properties, polyoxazolidinones, which are accessible from the reaction of ...

Epoxidation of propylene on NaCl-modified silver catalysts with air as the oxidant

open access: yes, 2002
Propylene epoxidation by air was carried out on NaCl-modified silver (NaCl/Ag) catalysts, and the catalysts were characterized by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The effects of NaCl loadings, propylene to oxygen ratio,

Dimethyldioxirane Epoxidation of 6,6-Disubstituted Fulvenes

open access: yes, 1991
The endocyclic bis-epoxides of various pentafulvenes were readily prepared by epoxidation with excess dimethyldioxirane; stoichiometric epoxidation yielded mixtures of the bis-epoxides and the labile mono-epoxides, but no exocyclic epoxides were observed.

Synthesis and Activity‐Based Protein Profiling Identifies Aldo‐Keto Reductase 1C3 as Target Protein of Myxoglucamides

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 41, 5 October 2026.
Myxoglucamide A—a novel glycolipopeptide isolated from myxobacteria—was synthesized, and activity‐based protein profiling identified aldo‐keto reductase 1C3 (AKR1C3) as its main target in human cells. Structure‐activity relationship studies, together with biophysical characterization and X‐ray crystallography, elucidated the structural basis of AKR1C3 ...

Styrene epoxidation over gold supported on different transition metal oxides prepared by homogeneous deposition-precipitation

open access: yes, 2004
Epoxidation of styrene by anhydrous tert-butyl hydroperoxide over a number of transition metal oxide (viz. TiO2, Cr2O3, MnO2, Fe2O3, Co3O4, NiO, CuO, ZnO, Y2O3, ZrO2, La2O3 and U3O8) supported nano-size gold catalysts, prepared by the homogeneous ...
