Polydentate ligands with benzene-o-dithiolato donor groups are useful building blocks in supramolecular coordination chemistry. The coordination chemistry of bis- and tris(benzene-o-dithiolato) ligands and mixed benzene-o-dithiolato/catecholato ligands is reviewed. These ligands exhibit a versatile coordination chemistry both in solution and in the solid state.

Carbon-hydrogen (C-H) bonds are the foundation of essentially every organic molecule, making them an ideal place to do chemical synthesis. The key challenge is achieving selectivity for one particular C(sp)-H bond. In recent years, metalloenzymes have been found to perform C(sp)-H bond functionalization.

A chemical reagent to access methyl sulfones has been developed. Its reaction with various bis-nucleophiles leads to the rapid formation of previously unknown heteroaromatic methyl sulfones. Analogous strategy can also be used to construct alkyl-, CHF-, CF- and even bicyclo[1.

Oxidative stress arises from an imbalance between reactive species (RS) production and the antioxidant defense, increasing the brain susceptibility to neurodegenerative and psychiatric diseases. Besides, changes in the expression or activity of neurotransmitter metabolism enzymes, such as monoamine oxidases (MAO), are also associated with mental disorders, including depression. Considering this, antioxidant and MAO-A activity inhibitory potential of six 2,3-chalcogenodihydrobenzofurans (2,3-DHBF) was investigated through in vitro and in silico tests.

Titanium (Ti)-based MOFs are promising materials known for their porosity, stability, diverse valence states, and a lower conduction band (CB) than Zr-MOFs. These features support stable ligand-to-metal charge transfer (LMCT) transitions under photoirradiation, enhancing photocatalytic performance. However, Ti-MOF structures remain a challenge owing to the highly volatile and hydrophilic nature of ionic Ti precursors.

Two novel 3D inorganic-organic hybrids based on [VO]/[VO] clusters, [Cu(bbpy)(VO)]·3HO () and [CuAg(pty)(VO)]·HO () (bbpy = 3,5-bis(1-benzimidazole) pyridine, pty = 4'-(4″-pyridyl)-2,2':6',2″-terpyridine), were isolated in the same POV/Cu/N-heterocycle ligand reaction systems. Hybrids and possess novel three-dimensional bimetallic frameworks derived from [VO]/[VO] clusters and Cu-organic complexes. In , bbpy ligands are grafted by Cu to a grid ribbon 2D sheet, which are connected with benzene-like [VO] to yield a 3D framework.
