Boehmite nanoparticles were prepared by very simple and inexpensive procedure in water at room temperature using commercially available materials. Two Schiff-base complexes of nickel have been immobilized on the boehmite nanoparticles. These catalysts were characterized by FT-IR spectroscopy, TGA, XRD, BET, UV-DRS, TEM, SEM, EDS and ICP-OES techniques. These compounds were applied as catalysts for the oxidation of sulfides to sulfoxides and oxidative coupling of thiols to disulfides under mild reaction conditions at room temperature. These catalysts were recovered by simple filtration and reused several times without significant loss of their catalytic efficiency.
Copper-catalyzed chalcogenation of aryl iodides via reduction of chalcogen elements by aluminum or magnesium
Taniguchi, Nobukazu
, p. 10510 - 10515,6 (2012)
Aluminum-induced copper-catalyzed coupling of aryl iodides with selenium or sulfur element could afford the corresponding diaryl selenides or sulfides in good yields. When magnesium chloride as an additive was employed, diaryl monoselenides and monosulfides were selectively obtained. On the contrary, the use of sodium carbonate produced diaryl diselenides and disulfides. The preparation of diaryl diselenides was necessary for magnesium as a reductant. Regrettably, tellurium was very low reactivity.
An efficient and convenient method for preparation of disulfides from thiols using air as oxidant catalyzed by Co-Salophen
Chai, Pin Ji,Li, Yong Shu,Tan, Cheng Xia
, p. 1403 - 1406 (2011)
Disulfides have been synthesized by oxidation of thiols using air as oxidant catalyzed by Co-Salophen with high yields, mild and neutral conditions, and easy procedures of the catalyst. The products were confirmed by 1H NMR and IR.

This study rationally designed a heterogeneously catalyzed system (i.e., using Ni-Pd alloy nanoparticles supported on hydroxyapatite (Ni-Pd/HAP) under an H2atmosphere) achieving an efficient base-free formal C-S bond metathesis of various thiolsviasuppression of the Ni catalysis deactivation.
Oxidation in fluoro alcohols: Mild and efficient preparation of disulfides from thiols
Kesavan, Venkitasamy,Bonnet-Delpon, Daniele,Begue, Jean-Pierre
, p. 223 - 225 (2000)
Quantitative oxidative conversion of thiols to disulfides was effected by aqueous 30% H2O2 in trifluoroethanol at ambient temperature under neutral conditions.
Fe3O4@S-ABENZ@VO: Magnetically separable nanocatalyst for the efficient, selective and mild oxidation of sulfides and oxidative coupling of thiols
Rezaei, Somaieh,Ghorbani-Choghamarani, Arash,Badri, Rashid,Nikseresht, Ahmad
, (2018)
Oxovanadium(IV) immobilized on Fe3O4@S-ABEN is reported as a highly efficient nanocatalyst for the oxidation of sulfides and oxidative coupling of thiols (using H2O2 as green oxidant), the products of which are obtained in high to excellent yields. The products can be separated by a simple extraction with organic solvent and the catalyst is highly efficient, especially in terms of selectivity of desired product. The catalytic system can be recycled and reused without significant loss of catalytic activity.
Flavin/I2-Catalyzed Aerobic Oxidative C–H Sulfenylation of Aryl-Fused Cyclic Amines
Jiang, Xinpeng,Zhao, Zongchen,Shen, Zhifeng,Chen, Keda,Fang, Liyun,Yu, Chuanming
, p. 3889 - 3895 (2020)
We report an aerobic oxidative C–H sulfenylation of aryl-fused cyclic amines with various thiols catalyzed by flavin/I2 for the first time. While flavin I catalyzed the C–H sulfenylation of indolines to afford 3-sulfenylindoles, flavin II enabl
Isolation of stable non cyclic 1,2-disulfoxides. Revisiting the thermolysis of S-aryl sulfinimines
Souto, José A.,Lewis, Willian,Stockman, Robert A.
, p. 12630 - 12632 (2014)
The thermolysis of S-aryl sulfinimines is shown to generate 1,2-disulfoxides and disulfides via initial Cope elimination, dimerisation of the produced sulfenic acid to a thiosulfinate, and subsequent disproportionation of the thiosulfinate. This journal is
Biomimetic methane generation and disulfide formation by catalysis with a nickel complex
Tada, Masaru,Masuzawa, Yoshihide
, p. 2161 - 2162 (1997)
The final metabolic process of methanogen, methane generation and simultaneous disulfide formation, is simulated by the reaction of thioanisole with a toluenethiyl radical in the presence of a nickel complex, which is generated by the photolysis of a toluenethiolato-nickel complex.
