Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

Tuning the Photochemistry of Entatic State Model Systems

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

British Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

Patch Testing in Individuals With Diabetes Using Medical Devices. Part 1—Contact Allergy to Baseline Series Allergens

Contact Dermatitis, EarlyView.
The contact allergy prevalence in individuals with diabetes and in diabetes medical device (MD) users is unknown. This study in 204 diabetes MD users (114 with rash to diabetes MDs, 90 without) aimed at investigating the contact allergy prevalence to baseline series allergens. Contact allergies to sesquiterpene lactone mix and myroxylon pereirae resin (

Patch Test Results With the European Baseline Series, 2021/2022—Joint European Results of the ESSCAA and the EBSB Working Groups of the ESCD, and the GEIDACC

Contact Dermatitis, EarlyView.
ABSTRACT Background Patch test results obtained with the European Baseline Series (EBS) in its current version serve both contact allergy surveillance and (re‐)assessing the diagnostic value of EBS allergens. Objectives To present results of current EBS patch testing, obtained in 59 departments in 14 European countries during 2021 and 2022.

Occurrence and Washout of Health‐Hazardous Chemicals in Children's Clothing

Contact Dermatitis, EarlyView.
A survey of 60 children's garments from the Swedish market showed a varying, often highly complex chemical content. The highest levels were generally found in synthetic materials and the lowest in light‐coloured cotton. Further, the washout effect by laundry and sweat migration of textile chemicals was investigated.

Characterisation of Sex Pheromone and Genetic Strain in Rachiplusia nu (Lepidoptera: Noctuidae) Populations Across Brazil

Journal of Applied Entomology, EarlyView.
ABSTRACT Rachiplusia nu, known as the sunflower looper (SFL) and belonging to the Plusiinae subfamily, is a major defoliator of soybeans, sunflowers and other horticultural crops across southern South America. This species has recently expanded to central and northern regions of Brazil, becoming a key soybean pest.
