《Metal-free synthesis of 3-chalcogenyl chromones from alkynyl aryl ketones and diorganyl diselenides/disulfides mediated by PIFA》 was published in Organic Chemistry Frontiers in 2020. These research results belong to Ai, Zhenkang; Xiao, Jiaxi; Li, Yadong; Guo, Boying; Du, Yunfei; Zhao, Kang. Reference of 1,2-Diphenyldisulfane The article mentions the following:

The 3-selenyl/sulfenyl chromones/thiochromones I (R = Ph, Me, 4-chlorophenyl, etc.; R1 = H, 7-Me, 6-Cl, 5-CF3, etc.; R2 = Ph, cyclopropyl, thiophen-3-yl, etc.) were conveniently synthesized from the PIFA-mediated reactions between alkynyl aryl ketones bearing an ortho-methoxy/methylthio group R1-2-XMe-C6H3C(O)CCR2 and diorganyl diselenides/disulfides RYYR (Y = Se/S). This metal-free approach is postulated to first undergo the formation of the reactive RSeOCOCF3 or RSOCOCF3 from the reaction of diorganyl diselenides or disulfides with PIFA, followed by the electrophilic cyclization of alkynyl aryl ketones enabled by the electrophilic species generated herein. In the part of experimental materials, we found many familiar compounds, such as 1,2-Diphenyldisulfane(cas: 882-33-7Reference of 1,2-Diphenyldisulfane)

1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. Reference of 1,2-Diphenyldisulfane They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however.

Thioxanthonation of di-Ph units of di-Ph disulfide was achieved successfully. The photoreduction and photostabilization ability of 2, 2′-disulfanediylbis (9H-thioxanthen-9-one) was used for in-situ preparation of Au nanoparticles either in solution or in poly(ethylene glycol) Me ether acrylate/poly(ethylene glycol) diacrylate polymer matrix. SPR(Surface Plasmon Resonance) absorption band of formed Au NPs were recorded at 550 nm by UV-vis spectroscopy. Indeed, formation of elliptical shaped nanoparticles (4-8μm) as well as spherical ones (11-14 nm) in nanocomposite films were obtained depending on UV irradiation time. DLS (Dynamic Light Scattering) measurements also changed from 440 nm to about 200 nm as a function of irradiation time. The potential of Au NPs/polymer nanocomposite film as a sensing element for benzene, toluene, xylene (BTX) sensing was studied at different temperatures An overall evaluation of the exptl. results showed that Au NPs/ polymer nanocomposite film has good potential as a sensing element for the detection of BTX vapors.

Recommanded Product: 1,2-DiphenyldisulfaneIn 2019 ,《Biomimetic catalytic oxidative coupling of thiols using thiolate-bridged dinuclear metal complexes containing iron in water under mild conditions》 was published in Catalysis Science & Technology. The article was written by Zhang, Yahui; Yang, Dawei; Li, Ying; Zhao, Xiangyu; Wang, Baomin; Qu, Jingping. The article contains the following contents:

Thiolate-bridged heterobimetallic half-sandwich complexes [Cp’M1(μ-SCH2CH2SCH2CH2S)M2Cp*][X] (2-PF6, Cp’ = C5Me5, M1 = Ru, M2 = Fe; 4a-BPh4, Cp’ = C5Me5, M1 = Fe, M2 = Co; 4b-BPh4, Cp’ = C5HMe4, M1 = Fe, M2 = Co) were prepared as catalysts for aerial oxidative coupling of thiols into disulfides. A green and efficient approach to disulfides via oxidative coupling of thiols was developed by adopting a biomimetic thiolate-bridged iron-ruthenium complex as the catalyst. Using environmentally friendly oxygen as the oxidant, a wide range of thiols including biol. important mols. can be smoothly converted into corresponding disulfides in water. Notably, two potential intermediate species were successfully isolated and unambiguously characterized, which is essential to reveal the detailed mechanism of this transformation. This catalytic system represents a rare and desired heteronuclear bimetallic scaffold for understanding the biol. process of S-S bond formation from the viewpoint of bioinspired catalysis. In addition to this study using 1,2-Diphenyldisulfane, there are many other studies that have used 1,2-Diphenyldisulfane(cas: 882-33-7Recommanded Product: 1,2-Diphenyldisulfane) was used in this study.

Wang, Deqiang; Ding, Wanjian; Hou, Guohua; Zi, Guofu; Walter, Marc D. published their research in Chemistry – A European Journal in 2021. The article was titled 《Uranium versus Thorium: Synthesis and Reactivity of [η5-1,2,4-(Me3C)3C5H2]2U[η2-C2Ph2]》.Synthetic Route of C12H10S2 The article contains the following contents:

The synthesis, electronic structure, and reactivity of a uranium metallacyclopropene were comprehensively studied. Addition of diphenylacetylene (PhCCPh) to the uranium phosphinidene metallocene [η5-1,2,4-(Me3C)3C5H2]2U:P-2,4,6-tBu3C6H2 (1) yields the stable uranium metallacyclopropene, [η5-1,2,4-(Me3C)3C5H2]2U[η2-C2Ph2] (2). Based on d. functional theory (DFT) results the 5f orbital contributions to the bonding within the metallacyclopropene U-(η2-C:C) moiety increases significantly compared to the related ThIV compound [η5-1,2,4-(Me3C)3C5H2]2Th[η2-C2Ph2], which also results in more covalent bonds between the [η5-1,2,4-(Me3C)3C5H2]2U2+ and [η2-C2Ph2]2- fragments. Although the thorium and uranium complexes are structurally closely related, different reaction patterns are therefore observed For example, 2 reacts as a masked synthon for the low-valent uranium(II) metallocene [η5-1,2,4-(Me3C)3C5H2]2UII when reacted with Ph2E2 (E = S, Se), alkynes and a variety of hetero-unsaturated mols. such as imines, ketazine, bipy, nitriles, organic azides, and azo derivatives In contrast, five-membered metallaheterocycles are accessible when 2 is treated with isothiocyanate, aldehydes, and ketones.1,2-Diphenyldisulfane(cas: 882-33-7Synthetic Route of C12H10S2) was used in this study.

The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Synthetic Route of C12H10S2
