Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

Small, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

Smart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.

Unraveling the effect of topological structures of B/N‐doped conjugated macrocycles on spectral properties: A computational study

Smart Molecules, EarlyView.
Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.

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.

Designing Tailored Molecular Cavities Using Calix[5]arenes as Building Blocks

The Chemical Record, EarlyView.
This account focuses on the shape and dimensions of cavities formed by precisely designed molecular frameworks. It highlights our efforts to construct synthetically tailored cavities based on calix[5]arenes. This study examines the shapes and dimensions of cavities defined by well‐designed molecular structures.

Dimethyl‐, Diethyl‐, and Propylene Carbonates: An Emerging Class of Green Solvents for Organic Synthesis

The Chemical Record, EarlyView.
This review highlights recent advances in the use of organic carbonates, dimethyl carbonate (DMC), diethyl carbonate (DEC), and propylene carbonate (PC), as solvents in organic synthesis. Based on over seventy studies from the past 6 years, it shows their application in different organic reaction types, emphasizing their role in safer and more ...
