Properties of [Fe(salen)]2‐μ‐Oxo Derivatives and Their Effect on Catalytic Hydrophosphination

European Journal of Organic Chemistry, EarlyView.
A series of [Fe(salen)]2‐μ‐oxo and [Fe(salophen)]2‐μ‐oxo complexes were synthesized to probe how ligand electronics and backbone rigidity influence redox behavior and catalytic hydrophosphination of styrene. Electron‐withdrawing substituents enhance stability and activity, enabling tunable, efficient C–P bond formation.

Probing Chiral Recognition on Amylose Tris(3,5‐Dimethylphenylcarbamate) Using Cinnamyl 2‐Aminoanilides: The Subtle Impact of Aliphatic Substituents

ELECTROPHORESIS, EarlyView.
This study investigates how subtle aliphatic substituent differences in racemic cinnamyl 2‐aminoanilides affect chiral recognition on amylose tris(3,5‐dimethylphenylcarbamate). Pronounced enantioselectivity changes arose from minimal structural variations. Mobile phase effects were examined, with 2‐propanol improving resolution.

Protein‐Based High‐Performance Liquid Chromatography and Cyclodextrin‐Capillary Electrokinetic Chromatography for the Chiral Separation of Azoles

ELECTROPHORESIS, EarlyView.
Human serum albumin‐based high‐performance liquid chromatography and cyclodextrin‐based capillary electrokinetic chromatography were used for the chiral separation of azoles. Although only two of the five tested azoles could be enantioseparated by liquid chromatography, all of them were separated by capillary electrokinetic chromatography using single ...

Bioassay-guided isolation and identification of antimicrobial compounds from thyme essential oil by means of overpressured layer chromatography, bioautography and GC-MS

, 2012
A simple method is described for efficient isolation of compounds having an antibacterial effect. Two thyme (Thymus vulgaris) essential oils, obtained from the market, were chosen as prospective materials likely to feature several bioactive components ...

Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

FlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...

Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies

International Journal of Cancer, EarlyView.
ABSTRACT Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely unknown, but environmental pesticide exposures are likely to contribute. Chronic low‐dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities.

Organic Phase Change Nanoparticles for in-Product Labeling of Agrochemicals

, 2015
There is an urgent need to develop in-product covert barcodes for anti-counterfeiting of agrochemicals. This paper reports a new organic nanoparticle-based in-product barcode system, in which a panel of organic phase change nanoparticles is added as a ...
