Synthesis and Structural Study of Iodonium Ylides Derived From 2‐Iodosylbenzenesulfonic Acid: Reagents for Preparation of Annulated Thiazoles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
New ylides of two different types were prepared by reaction of 2‐iodosylbenzenesulfonic acid with the corresponding 1,3‐cyclohexanediones under acidic or basic conditions. These compounds have a typical for iodonium ylides structure with the CIC angles 94.18° –97.25° and the IC bond distances between 2.08 and 2.13 Å.

Sustainable Iron Catalysis for Chemodivergent Oxidation of Lignin‐Based Vanillyl Alcohol: Selective Access to Vanillin and Vanillic Acid

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Green reaction media enable chemodivergent oxidation of vanillyl alcohol, selectively affording vanillin or its fully oxidized counterpart, vanillic acid. The use of an earth‐abundant, inexpensive, and nontoxic iron catalyst for the transformation of lignin‐derived alcohol to fine chemicals underscores the sustainability of the process. A low E‐factor (

Modular π‐Extended IF‐TTF Systems: Tuning Redox and Optical Properties in Donor–Acceptor and Donor–Donor Frameworks

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Donor–acceptor and donor–donor systems incorporating an indeno[1,2‐b]fluorene‐extended tetrathiafulvalene (IF‐TTF) donor motif were prepared by Suzuki coupling reactions. The compounds were studied for their optical and redox properties. The compounds showed multiredox behavior with several accessible redox states. A series of π‐extended donor–acceptor

Quality of Spontaneous and Backslopped Fermented Cassava Flour From Different Cassava Landraces and Sensory Acceptability of the Cooked Dough

open access: yesFood Chemistry International, EarlyView.
The cooked Oko‐iyawo spontaneously fermented cassava flour's sensory acceptability was correlated with its amylose content, pH, pasting temperature, and water absorption capability. Cassava processors may be able to create consistently high‐quality fermented cassava flour for various end users with the use of the information provided in this study ...

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

open access: yesFlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

The research progress in polyethylene oxide polymer electrolytes

open access: yesFlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Marine Macroalgae as a Safe Healthy Food While Meeting Food Security Challenges Arising From Climate Changes

open access: yesFood Safety and Health, EarlyView.
Planned harvesting and processing of marine macroalgae could meet future global food needs and mitigate fuel‐originated carbon dioxide responsible for climate change. Microalgal foods are nutritious and safe. The utilization of macroalgae would avoid environmental problems arising from the release of overgrowing macroalgae caused by heatwaves, which ...

Local Structures of Se and Br in Cretaceous–Paleogene Boundary Sediments and Concentration Effects of Ferrihydrite Originating From Impact Ejecta

open access: yesGeological Journal, EarlyView.
Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.
