Organic chemistry has seen a surge in visible-light-driven transformations, which offer unique reaction pathways and access to new synthetic possibilities. We aim to provide a comprehensive understanding of state-of-the-art photo-mediated alkyne functionalization, with a focus on the reactive behavior of vinyl radicals. This review outlines our contributions to the field, including developing new methods for forming carbon-carbon and carbon-heteroatom bonds.

Infections caused by fungal pathogens are a global health problem, and have created an urgent need for new antimicrobial strategies. This report details the synthesis of lipidated 2-vinyl-4,4-dimethyl-5-oxazolone (VDM) oligomers an optimized Cu(0)-mediated reversible-deactivation radical polymerization (RDRP) approach. Cholesterol-Br was used as an initiator to synthesize a library of oligo-VDM (degree of polymerisation = 5, 10, 15, 20, and 25), with an α-terminal cholesterol group.

Selective coupling of C platform molecules to C olefins is a cornerstone for establishing a sustainable chemical industry based on nonpetroleum sources. Vinyl chloride (CHCl), one of the top commodity petrochemicals, is commercially produced from coal- or oil-derived C hydrocarbon (acetylene and ethylene) feedstocks with a high carbon footprint. Here, we report a C-based route for vinyl chloride synthesis via the selective oxidative coupling of methyl chloride.

The contamination of water systems by antibiotics such as ciprofloxacin (CIP), which is used to treat bacterial infections, poses severe risks to environmental safety and public health. To address this issue, a novel zwitterionic polymeric nanocomposite (PNs-HTC) was developed in this study. This novel material was synthesized using alkylated chitosan ionic macromonomers, ionic monomers and combined with hydrotalcite (HTC) via in situ free radical polymerization.

Supercritical water gasification (SCWG) is famous for the clean utilization of organic wastes without SO emission. Investigating the decomposition mechanism of sulfone compounds, the dominant organic sulfur compounds of organic wastes, in supercritical water (SCW) is conducive to the development of SCWG technology. Herein, the comparative decomposition mechanism of phenyl vinyl sulfone (PVS), diphenyl sulfone (DS), and benzo[b]thiophene 1,1-dioxide (BD) are explored via experiments and density functional theoretical (DFT) calculations.

The macroscopic properties of elastomers are intimately linked to their molecular reactivity and mechanisms. Here, we propose a new strategy for designing strengthening materials based on the synergy of weak covalent bonds and mechanochemistry. After mechanical treatment, the failure strength and toughness of the elastomer increased from 2.
