The first example of the synthesis of planar chiral (1,3-disubstituted arene)Mn(CO)3+ cations (3) has been demonstrated by a reaction of (p-cresol)Mn(CO)3+ with KOBut followed by addition of nucleophiles and subsequent quenching with electrophiles in the presence of (S)-binaphthol in CH2Cl2.

Planar chirality found tremendous use in many fields, such as chemistry, optics, and materials science. In particular, planar chiral [2.2]paracyclophanes (PCPs) are a type of structurally interesting and practically useful chiral compounds bearing unique electronic and photophysical properties and thus have been widely used in π-stacking polymers, organic luminescent materials, and as a valuable toolbox for developing chiral ligands or organocatalysts.

Optically pure monosubstituted [n]paracyclophanes are promising candidates for material synthesis, asymmetric catalysis, and drug discovery. Thus far, only a few catalytic asymmetric synthesis processes have been reported for assessing these stained atropisomers. In this study, we describe a highly enantioselective synthesis of monosubstituted [n]paracyclophanes by combining desymmetrization and kinetic resolution.

Seven-membered nitrogen-containing heterocycles, particularly azepine-based compounds, represent an intriguing class of molecules with vast arrays of applications. These compounds have garnered considerable attention in synthetic and medicinal chemistry due to their non-planar, non-aromatic features, which offer structural flexibility and diversity to design new drugs with improved pharmacological properties. This review summarizes the recent advances in the synthesis of azepine derivatives, including eco-friendly methodologies that align with the principles of green chemistry, which emphasize atom economy, sustainability, and waste reduction.

The Friedel-Crafts reaction has been extensively applied to the preparation of various porous organic polymers because of its simple operation and abundant building blocks. However, due to its poor reversibility and excessive random reactive sites, the synthesis of crystalline organic polymers/frameworks by Friedel-Crafts reaction has never been realized so far. Herein, we develop a molecular confined Friedel-Crafts reaction strategy to achieve rapid preparation (within only 30 minutes) of highly crystalline covalent triazine frameworks (CTFs) with tailorable functionality for the first time.

Electrically conductive coordination polymers (ECCPs), particularly those incorporating benzenehexathiol (BHT) ligands, are emerging as a distinctive class of electronic materials with tunable semiconducting and metallic properties. However, the exploration of novel ECCPs with low-symmetry structures and electrical anisotropy remains under development. Here, we report the on-water surface synthesis of a novel ECCP, namely Cu5BHT, which exhibits a low-symmetry structure and unique in-plane electrical anisotropy that differs from the well-known Cu3BHT phase.
