《Alternating Current Electrolysis for the Electrocatalytic Synthesis of Mixed Disulfide via Sulfur-Sulfur Bond Metathesis towards Dynamic Disulfide Libraries》 was published in Chemistry – A European Journal in 2020. These research results belong to Sattler, Lars Erik; Otten, Chris Josef; Hilt, Gerhard. Safety of 1,2-Diphenyldisulfane The article mentions the following:

A novel approach of electrolysis using a.c. was applied in the S-S bond metathesis of sym. disulfides towards unsym. disulfides. As initially expected, a statistical distribution in disulfides was obtained. Also, the influence of electrode polarization by a.c. was studied on a two-disulfide matrix. The highly dynamic nature of this chem. resulted in the creation of dynamic disulfide libraries by expansion of the matrixes, consisting of up to six sym. disulfides. Mixing of matrixes and stepwise expanding of a matrix by using a.c. electrolysis were realized.

Quality Control of 1,2-Diphenyldisulfane And the article was included in Journal of Organic Chemistry in 2020. The article conveys some information:

An efficient two-component copper-catalyzed cyclization cascade approach toward highly functionalized indolizinone heterocycles has been developed from reactions of pyridine-, isoquinoline-, and quinoline ynones, via 5-exo-dig cyclization. The catalysis involves the activation by diorgano diselenide and diorgano disulfide and also their incorporation into the indolizinone core. In addition, the obtained substituted indolizinones were readily transformed into 1-(organochalcogenyl)indolizin-2-ols, which are important building blocks in organic synthesis. In addition to this study using 1,2-Diphenyldisulfane, there are many other studies that have used 1,2-Diphenyldisulfane(cas: 882-33-7Quality Control of 1,2-Diphenyldisulfane) was used in this study.

Tang, Shuai; Chen, Qiliang; Si, Yubing; Guo, Wei; Mao, Bingwei; Fu, Yongzhu published their research in Advanced Materials (Weinheim, Germany) in 2021. The article was titled 《Size Effect of Organosulfur and In Situ Formed Oligomers Enables High-Utilization Na-Organosulfur Batteries》.Application of 882-33-7 The article contains the following contents:

Organosulfurs are promising cathode materials for rechargeable metal batteries due to their high capacities, diverse structures, and electrochem. properties. Herein, the electrochem. behavior of three organosulfur compounds, i.e., 4,4′-thiobisbenzenethiol (TBBT), 1,4-benzenedithiol (1,4-BDT), and di-Ph disulfide (DPDS), is revealed in room-temperature rechargeable sodium (Na) batteries, which show significantly improved performances when sodiated Nafion membranes are used. Large oligomers of organosulfur can be formed during charging, and they are readily blocked by the nanosized ion-conducting clusters in the Nafion membrane. In addition, large organosulfur monomers can also be blocked. Only 5.4% of TBBT diffuses through the Nafion membrane after 800 h. The Na|TBBT cell sustains 77% of the theor. capacity after 300 cycles (2420 h). Moreover, the Na|TBBT redox flow cell shows promising rechargeability. Due to the medium mol. size, the organosulfur oligomers are expected to provide a new avenue to develop high-capacity chalcogen cathodes, besides inorganic S and S-containing polymers.

And the article was published in Asian Journal of Organic Chemistry in 2019. Application of 882-33-7 The author mentioned the following in the article:

A metal-free sequential one-pot three-component protocol is described for the synthesis of C3-functionalized imidazo[1,2-a]pyridines. A successive construction of imidazo[1,2-a]pyridine I (R = 4-MeC6H4, 2-naphthyl, 2-thienyl, etc.; R1 = SMe, naphthalen-1-ylsulfanyl, pyridin-2-ylsulfanyl, etc.; X = H, 6-Br, 6-Cl, 7-Me, 8-Me) followed by iodine-catalyzed sulfenylation has been achieved in a one-pot operation from readily available α-bromomethyl ketones RC(O)CH2Br, 2-aminopyridines II and thiosulfonates R1S(O)2Ar (Ar = C6H5, 1-naphthyl, 2-thienyl, etc.). An immense array of 3-sulfenylimidazo[1,2-a]pyridines I was obtained in good to high yields. Also, the method is extended for the synthesis of C3-halogenated imidazo[1,2-a]pyridines I (R1 = Br, Cl) using sodium halides NaY in the presence of K2S2O8. Notably, the reaction between α-bromomethyl ketones and 2-aminopyridines in the presence of K2S2O8 to yields 3-bromo-2-aryl-imidazo[1,2-a]pyridines I (R1 = Br), thus implying α-bromomethyl ketones to be served as brominating agent. Overall, the present sequential one-pot protocol is straightforward, operationally simple, tolerates a broad range of functional groups, and is reliable for gram-scale experiments In the experimental materials used by the author, we found 1,2-Diphenyldisulfane(cas: 882-33-7Application of 882-33-7)

《Devulcanization of natural rubber industry waste in supercritical carbon dioxide combined with diphenyl disulfide》 was written by Asaro, Lucia; Gratton, Michel; Poirot, Nathalie; Seghar, Said; Ait Hocine, Nourredine. COA of Formula: C12H10S2 And the article was included in Waste Management (Oxford, United Kingdom) in 2020. The article conveys some information:

The elimination of rubber wastes without affecting the environment is one of the most important challenges of the 21st century waste management. Accordingly, the present work is focused on the recycling of natural rubber (NR) industry waste by means of devulcanization in supercritical carbon dioxide (scCO2) atm. With that aim, a novel device allowing to perform rubber devulcanization was developed. It consists of a triaxial compression reactor integrated into a dynamic hydraulic universal testing machine with a heating chamber. NR industry waste was devulcanized in the mentioned device at different temperatures, in scCO2 by using di-Ph disulfide (DD) as devulcanizing reagent. The devulcanization degree and quality of the treated materials were evaluated by the swelling test combined with the Horikx theory. It was appeared that a successful devulcanization, with almost no degradation, was obtained, and the devulcanization degree reached maximum value of ∼90%. Thermogravimetric tests and SEM (SEM) images strengthened these results. Finally, it was concluded that the developed device is appropriate to perform rubber recycling, which contributes to the progress in the environmental protection. In the experimental materials used by the author, we found 1,2-Diphenyldisulfane(cas: 882-33-7COA of Formula: C12H10S2)

1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. COA of Formula: C12H10S2 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.
