On the Nature of Improper Hydrogen Bonding in RCH2F and RCHF2 Motifs
The nature of ‘improper’ hydrogen bonds is explored in FnC─H⋯X systems, such as RCF2H interaction with chloride and water. It is noted that increased fluorination decreases the positive charge density on H but increases it on C, thus these interactions are dominated by electrostatic attraction to C over H.

The integration of metal nanoclusters (MNCs) with reticular frameworks (RFs) has recently emerged as a powerful strategy to create composite materials with enhanced and synergistic functionalities. This review provides an overview of the synthetic strategies developed for constructing MNCs/RFs composites and their recent advances in biomedical ...

Myths and Truths About Electrophilic Aromatic Substitution: The Particular Case of Fluorobenzene
Nitration σ‐complex formation is exothermic, and halogens—particularly fluorine—enhance para reactivity, challenging traditional descriptions of halogens as purely deactivating in EAS. ABSTRACT Electrophilic aromatic substitution (EAS) is a fundamental reaction introduced early in organic chemistry courses, highlighting the influence of substituents on

Understanding β-Hydride Eliminations from Heteroatom Functional Groups [PDF]
Using density functional theory, we investigated detailed aspects of the quintessential organometallic process, β-hydride elimination (BHE). In general, we find that most BHE processes from alkyl functional group β-atoms are facile, while BHE processes ...

Direct C─H Lactonization of Carboxylic Acids Enabled by LMCT Photoactivation
We report a photochemical method for oxidative γ‐C─H lactonization of simple carboxylic acid substrates upon LMCT photoactivation. Intriguingly, these conditions suppress the rapid decarboxylation characteristic of oxidized carboxylates, suggesting the intermediacy of metal‐stabilized acyloxy radical instead of the dissociative process typically ...
