Ligand‐Controlled Tunable Distal C(sp2)–H Functionalization of Aryl and Benzyl Phosphonates

Transformative Chemistry, EarlyView.
The switchable borylation of aryl and benzyl phosphonates with good to excellent regioselectivity was demonstrated. Through orthogonal transformation of Horner–Wadsworth–Emmons olefination and Suzuki–Miyaura cross coupling, a variety of styrene derivatives were obtained with precise site control.

Predicting the Regioselectivity of Mechanochemical Bond Scission in Complex Molecules

Transformative Chemistry, EarlyView.
Covalent‐bond peak force network (CBPFNet), a physics‐informed graph attention framework, predicts mechanochemical bond scission regioselectivity directly from equilibrium structures with DFT‐level accuracy. By uncovering the ‘stiffness mismatch’ mechanism, this work enables the rational design of programmable mechanical fuses for next‐generation ...

Advances in the Different Synthetic Routes of Fluorinated Hydrazines

The Chemical Record, EarlyView.
This review highlights the various routes to the preparation of fluorinated hydrazines, thereby promoting the exploration of innovative methods for the synthesis of new N‐fluorinated hydrazines. Their synthesis mainly involves synthetic routes such as organometallic, organocatalytic, and photocatalytic.

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.

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

British Journal of Pharmacology, EarlyView.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...
