Convenient catalytic synthetic methods for the preparation of unsym. disulfanes RSSR1 (R = dodecyl, cyclohexyl, benzyl, furan-2-yl, etc.; R1 = Me, cyclohexyl, benzyl, pyridin-2-yl, etc.) are described. Na-exchanged X type zeolite (Na-X), com. available as MS-13X, effectively catalyzes thiol-disulfane exchange reactions with 1.0 equiv of thiols RSH and 2.5-3.0 equiv of disulfanes R1SSR1 at 10°C to room temperature under air. The reactions of sterically-hindered disulfanes or electron-deficient thiol substrates require high temperatures under inert atmospheres to maintain the good product yields. Various functionalized thiols and disulfanes are tolerant in the present catalytic systems, affording the corresponding unsym. disulfanes in good-to-high yields (up to 96%). The Na-X catalyst was successfully recycled 10 times without loss of yield.

In 2019,ChemPhysChem included an article by Demaison, Jean; Vogt, Natalja; Saragi, Rizalina Tama; Juanes, Marcos; Rudolph, Heinz Dieter; Lesarri, Alberto. Quality Control of 1,2-Diphenyldisulfane. The article was titled 《The S-S Bridge: A Mixed Experimental-Computational Estimation of the Equilibrium Structure of Diphenyl Disulfide》. The information in the text is summarized as follows:

The disulfide bridge (-S-S-) is an important structural motif in organic and protein chem., but only a few accurate equilibrium structures are documented. We report the results of supersonic-jet microwave spectroscopy experiments on the rotational spectra of di-Ph disulfide, C6H5-S-S-C6H5 (including all 13C and 34S monosubstituted isotopologues), and the determination of the equilibrium structure by the mixed estimation (ME) method. A single conformation of C2 symmetry was observed in the gas phase. This disulfide is a challenging target since its structure is determined by 34 independent parameters. Addnl., ab initio calculations revealed the presence of three low-frequency vibrations (<50 cm-1) associated to Ph torsions which would prevent the calculation of an accurate force field. For this reason, instead of the semiexperimental method, we used the mass-dependent (rm) method to fit the structural parameters concurrently to moments of inertia and predicate parameters, affected with appropriate uncertainties. The predicates were obtained by high-level quantum-chem. computations. A careful anal. of the results of different fits and a comparison with the ab initio optimizations confirms the validity of the used methods, providing detailed structural information on the title compound and the disulfide bridge. In the experimental materials used by the author, we found 1,2-Diphenyldisulfane(cas: 882-33-7Quality Control of 1,2-Diphenyldisulfane)

Computed Properties of C12H10S2In 2020 ,《Cryogenic grinding performance of scrap tire rubber by devulcanization treatment with ScCO2》 was published in Powder Technology. The article was written by Li, Xiang; Xu, Xiaofei; Liu, Zhijun. The article contains the following contents:

The cryogenic grinding performance of scrap tire rubber modified by devulcanization treatment in supercritical carbon dioxide (ScCO2) was studied with a fluidized-bed jet mill. Scrap tire rubbers devulcanized with various concentrations of devulcanizing reagents were ground to analyze the effect of the degree of devulcanization on the particle size distribution of the ground product. Population balance modeling based on selection and breakage functions was adopted to explore the evolution rule of the particle sizes in the grinding process. The results of the cryogenic grinding experiment show that the devulcanization treatment can promote particle size reduction and lead to the transformation of the grinding mechanism from abrasion to cleavage or fracture. Furthermore, Kapur function fitted by the population balance modeling was proposed with a cubic polynomial, and the calculation results agreed well with the exptl. data. In addition to this study using 1,2-Diphenyldisulfane, there are many other studies that have used 1,2-Diphenyldisulfane(cas: 882-33-7Computed Properties of C12H10S2) was used in this study.
