During the past few years, the construction of diarylethene (DAE)-based supramolecular metallacycles and metallacages has gained increasing attention due to their distinctive photophysical and photochemical properties and potential applications in magnetic switching, smart soft materials, photodynamic therapy, etc. Surprisingly, no review on the construction of discrete DAE-based supramolecular metallacycles and metallacages via coordination-driven self-assembly has been summarized to the best of our knowledge. Considering the rapid development of this field, it is time to summarize the recent development of the construction of discrete DAE-containing polygons and polyhedra. In this review, the construction of diarylethene-based metallacycles and metallacages via coordination-driven self-assembly is briefly introduced. In addition, the properties and applications of these metallacycles and metallacages are also discussed.

We report the unusual behavior of oxidosqualene sterol cyclase from pig liver towards 2,3-oxidosqualene analogs bearing two alkyl groups different from a methyl, at their Δ^18-19 double bond: unambiguous structure determinations of the products and tentative rational for their formation are described.

Organophosphorus compounds are of great significance in organic chemistry. Therefore, the construction of phosphorus-containing compounds has attracted significant attention from organic chemists. Radical phosphorylation has become a powerful strategy for building organophosphorus compounds and numerous achievements have been realized in recent years. In this review, we summarize the development of the generation and application of phosphorus radicals in organic chemistry since 2016. Special emphasis is given to various new transformations involving the generation of P-centered radicals via transition metal catalytic, photochemical and electrochemical means. Recent advances in the development of metal-free catalytic phosphorylations involving P-centered radicals are also reviewed.

Boron-containing compounds have a wide range of structures and rich and multifaceted reactivity patterns. As a result, these compounds are being increasingly used in organometallic, supramolecular, organic and inorganic chemistry, as well as in catalysis and materials science. This perspective describes recent ground-breaking studies and their implications for the future development of new catalysts and materials containing one or several trivalent boron atoms.
