Abstract Dihalogenation of alkenes to the high-added value vicinal dihalides is a prominent process in modern synthetic chemistry. However, their effective conversion still requires use expensive and hazardous agents, sacrificial half-reaction coupling or primary energy input. Here, we show photocatalytically assisted shuttle (p-shuttle) strategy for redox-neutral reversible dihalogenation using low-cost stable 1,2-dihaloethane under visible light illumination. Energetic hot electrons from...
The only known method for the dearomative trifluoromethoxylation of indoles is preliminary, with one substrate successfully undergoing reaction. In this study, we not developed a broadly applicable indole but also achieved divergent by fine-tuning reaction conditions. Under optimized conditions, silver salt and an easily handled OCF3 reagent, various smoothly underwent dearomatization to afford diverse array ditrifluoromethoxylated indolines in 50–84% isolated yields up 37:1...
Abstract The first example of a direct dehydroxytrifluoromethoxylation alcohols has been developed. This method generated an alkyl fluoroformate in situ from alcohols, followed by nucleophilic trifluoromethoxylation with trifluoromethyl arylsulfonate (TFMS) as the reagent. reaction is operationally simple and scalable, it proceeds under mild conditions to provide access wide range ethers alcohols. In addition, this suitable for late‐stage complex small molecules.
A novel triphenylphosphine-mediated direct trifluoromethylthiolation of indole derivatives using trifluoromethanesulfonyl chloride as the SCF<sub>3</sub> source was developed.
Abstract Methods for direct C-H trifluoromethoxylation of arenes and heteroarenes are rare, despite the importance trifluoromethoxylated compounds pharmaceuticals, agrochemicals, material sciences. Especially selective pyridines remains a formidable challenge. Here we show general late-stage as limiting reagent with trifluoromethoxide anion. The reaction is mediated by silver salts under mild conditions, exhibiting broad substrate scope wide functional-group compatibility. In addition, ortho...
Perovskite semiconductors as advanced solar energy-converting materials are promising catalysts for photoredox organic synthesis. Despite the high concentration of charge carriers generated on perovskite surface, efficient utilization these nonequilibrium and shambolic energetic to trigger a chemical reaction remains hot challenging subject. Here, we report photon-mediated electron shuttle between paired redox sites nanocrystals reformation highly stable carbon–halogen bonds, where both...
Iodine-catalysed regioselective sulfenylation of flavonoid derivatives with sulfonyl hydrazides was developed. Various thioethers were obtained in moderate to good yield. The thiolation could be conveniently directed C-8 for flavone, flavonol, dihydroflavone, and isoflavone or C-7 aurone by employing the isopropyl ethers flavonoids bearing free OH groups at C-5 C-4 positions.

Cellulose nanocrystals (CNCs) have triggered considerable research interest in the last few years owing to their unique optical, biodegradation, and mechanical behavior. Herein, recent progress on sensing application of photonic CNC films is summarized discussed based analyses latest studies. We briefly introduce three approaches for preparing CNCs: treatment, acid hydrolysis, enzymatic recapitulating differences preparation properties. Then, when aqueous suspension cellulose reaches a...
Abstract Regioselective aryl and alkyl thiolation reactions of flavonoid derivatives are described which proceed in position C‐8 for C‐5 hydroxylated flavone, flavonol, dihydroflavone, isoflavones derivatives, or 7 case C‐4 aurone derivatives.
