Synthesis of diaryl sulfides via nickel ferrite‐catalysed C─S bond formation in green media

“…We believe that the reaction involves a heterogeneous process and the catalysis may occur on the surface of the NiFe 2 O 4 MNPs. It is hypothesized that S 8 reacts with NaOH to produce sodium disulfide [16a]. Then, stable NiS is formed from the reaction of sodium disulfide with NiFe 2 O 4 MNPs.…”

“…To overcome these drawbacks, various persulfides (thiol surrogates) have been employed . Among sulfur sources, S 8 due to its being commercially available, of low cost, chemically stable, odourless and easy to handle has been successfully used . Although these efforts have improved the reaction conditions, most of these reported methods were performed under homogeneous and non‐recoverable reaction conditions.…”

Synthesis and Biological Evaluation of Novel L-Homoserine Lactone Analogs as Quorum Sensing Inhibitors of <i>Pseudomonas aeruginosa</i>

“…20) Moreover, the aromatic thioether group has long been used as a linker to connect different biologically active moieties in the design of novel compounds. [21][22][23] The phenylurea moiety has biological activities, including antibacterial, anticancer and insecticide 24) activities, and phenylurea derivatives have been found to be fungicidal against Rhizoctonia solani and Pellicularia spp. 25) Brominated furanones (BFs) are a leading class of anti-virulence compounds and have been proven to prevent the normal operation of the QS system, which competes with AHLs for a receptor protein.…”

Copper nanoparticles supported on polyaniline‐functionalized multiwall carbon nanotubes: An efficient and recyclable catalyst for synthesis of unsymmetric sulfides using potassium ethyl xanthogenate in water

“…Recently, thiourea, potassium thiocyanate, thiolates, carbon disulfide, sulfur powder, thioimide, sodium thiosulfate and ethyl xanthogenate have been reported as sulfur sources in C─S bond formation. However, these reactions are often conducted in dimethylformamide (DMF) at a high temperature.…”
