“…[3][4][5][6], we confirmed the formation of radical intermediates performing trapping experiments with the radical scavengers TEMPO (2,2,6,6-tetramethylpiperidine 1-oxyl) and BHT (2,6di-tert-butyl-4-methylphenol) (Scheme 2c). In the presence of 3 equivalents of BHT, the yield of the thiolated product 3 a dropped to 56% in CH 2 Cl 2 (standard condition B).…”

“…The HAT from the alkene 1 c (reaction [5] in SI-CD), although being exoergic (ΔG =-11.5 kcal mol À 1 ), is too slow (k 5 = 4.6 M À 1 s À 1 ) to compete with that of thiophenol 2 a, having a concentration in the same order of 1 c.…”

“…The synthesis of natural products, pharmaceuticals and organic materials are among the fields that could benefit more from the development of alternative catalyst-free, light-driven approaches. In this context, the growing interest in organosulfur compounds, including natural products, [3] drugs, [4] materials, [5] polymers [6] and synthetic intermediates, [7] has led to the search for novel methods for carbon-sulfur bond formation that overcome the limitations of traditional methodologies (high temperature, toxic solvents, harsh reaction conditions). [8] Considered a core methodology of modern chemistry, the thiol-ene reaction is a robust transformation allowing new carbon-sulfur bonds in an anti-Markovnikov fashion to be formed.…”

Here we present a catalyst‐free protocol for the purple light‐mediated anti‐Markovnikov functionalization of alkenes with thiols. Crucial to the generation of the thiyl radical was the formation of a key photo‐active complex. More than 30 thioether products were obtained, demonstrating tolerance towards different functional groups and scalability up to 5 mmol of alkene. Two different reaction conditions have been developed, varying both the solvent and the amount of thiol. Depending on the alkene structure, water can be used as an alternative to dichloromethane as a solvent, thus increasing the sustainability of the whole process.

Metrics & MoreArticle Recommendations CONSPECTUS:The success of lithium-ion batteries (LIBs) has driven the vigorous development of mobile electronic devices and electric vehicles. As a key component of LIBs, the energy density of traditional cathode materials has approached the theoretical limit, and the scarce transition metal elements have significantly increased the cost of batteries.In pursuit of cheap, abundant, and high-capacity materials, more attention is being focused on conversion-type cathodes. Sulfur (S), as a competitive nonmetallic element with extremely high theoretical capacity, has been widely studied in recent years. However, the poor conductivity of S and its discharge product, high solubility of the intermediate product polysulfides, and large volume change during cycling limit the practicality of S cathodes. Organosulfur materials, as a supplement to S cathodes, are considered promising organic electrode materials due to their high capacity, structural designability, and low cost. Unfortunately, the inherent high solubility and sluggish kinetics of organosulfur molecules hinder their further development. To break through the bottleneck faced by organosulfur compounds, various strategies have been adopted including conductive additives, electrocatalytic mediators, advanced electrolytes, and modified separators. Among them, the introduction of inorganic components can effectively regulate the characteristics of organosulfur molecules, thereby greatly improving the electrochemical performance of organosulfur batteries.In this Account, we first introduce the redox mechanism of organosulfur cathodes and provide a detailed discussion of the current development bottlenecks of organosulfur materials. Meanwhile, the strategy of improving the performance of organosulfur batteries through the construction of organic−inorganic composite cathodes is emphasized. In the design of organosulfur molecules, various heteroatoms such as N, O, and Se are introduced into the functional groups. The regulation of electronic structure and physicochemical properties at the molecular level can fundamentally manipulate the electrochemical performance of organosulfur.Second, the addition of conductive substrates like carbon nanotubes (CNTs) and reduced graphene oxide (rGO) with high conductivity and specific surface area provides rich conductive pathways and sufficient physical adsorption for organosulfur compounds. In addition, the introduction of a catalytic medium including transition metal sulfides and oxides can reduce the dissolution of soluble S species through strong polar adsorption and accelerate the conversion of organosulfur through electrocatalytic ability. Intermolecular or atomic interactions between active organosulfur groups and inorganic materials provide a simple and practical solution for improving the electrochemical performance of organosulfur materials. Finally, solutions to the challenges faced by organosulfur cathodes and the future development prospects of high-performance organosulfur batteries...

Rechargeable lithium metal batteries (LMBs) are promising next‐generation energy storage systems due to their high theoretical energy density. However, their practical applications are hindered by lithium dendrite growth and various intricate issues associated with the cathodes. These challenges can be mitigated by using organosulfur‐based mediators (OSMs), which offer the advantages of abundance, tailorable structures, and unique functional adaptability. These features enable the rational design of targeted functionalities, enhance the interfacial stability of the lithium anode and cathode, and accelerate the redox kinetics of electrodes via alternative reaction pathways, thereby effectively improving the performance of LMBs. Unlike the extensively explored field of organosulfur cathode materials, OSMs have garnered little attention. This review systematically summarizes recent advancements in OSMs for various LMB systems, including lithium–sulfur, lithium–selenium, lithium–oxygen, lithium‐intercalation cathode batteries, and other LMB systems. It briefly elucidates the operating principles of these LMB systems, the regulatory mechanisms of the corresponding OSMs, and the fundamentals of OSMs activity. Ultimately, strategic optimizations are proposed for designing novel OSMs, advanced mechanism investigation, expanded applications, and the development of safe battery systems, thereby providing directions to narrow the gap between rational modulation of organosulfur compounds and their practical implementation in batteries.
