Reversible Assembly and Disassembly of σ‐Aromatic B3 Rings

open access: yesChemistry – A European Journal, EarlyView.
B3 rings are the smallest σ‐aromatic boron compounds. Here, we show for the first time that cationic diboranes with an electron‐precise (2c,2e) bond can be reversibly converted to σ‐aromatic B3 rings with electron‐deficient (3c,2e) bonding. Base‐induced disassembly of the B3 ring leads back to cationic diboranes and monoborane adducts.

Mechanistic Insights Into Luminol Chemiexcitation: The Role of the Amide Carbonyls

open access: yesChemistry – A European Journal, EarlyView.
By means of quantum‐chemical calculations, we demonstrate that the 1,2‐dioxin ring forms following nitrogen release from parent luminol. We also identify alkoxide groups derived from the amide carbonyls of luminol as key enhancers of the chemiexcitation yield.

Getting the Big Ones to Pack: Crystal Structure of Vitamin K2 With a Chaperone

open access: yesChemistry – A European Journal, EarlyView.
A method for obtaining co‐crystals of medium‐size organic molecules and ‐tetrakis(2‐fluoro‐4‐methoxyphenyl)adamantane (TFM) as chaperone was developed. This method yielded a high‐resolution x‐ray crystal structure of menaquinone MK‐4 (vitamin K2), in which layers of chaperone and vitamin guest molecules are found.

A White Paper on Advancing Long‐Acting Therapeutics for Maternal and Pediatric Health by Bridging Gaps in Clinical Research, Access and Regulation

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
As use cases for long‐acting therapeutics expand across clinical indications, there is a critical need to ensure the inclusion of women who are pregnant or breastfeeding, infants and children—populations with a historical gap in the availability of interventions already approved for use in adults.

Digital and Gender Attributes of IC in Sustainability Reporting of Italian Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Italian listed enterprises increasingly rely on intellectual capital (IC) to enhance competitiveness and sustainability performance. As IC, comprising human, structural, and relational capital, is rarely recognised in financial statements due to the lack of standardised frameworks, its disclosure has gained relevance in sustainability ...
