, p. 16 - 21 (2012)
A convenient and facile catalytic oxidation of thiols to the corresponding disulfides is described using CoSalen as the catalyst and air as the oxidizing agent. This new approach provides an efficient method for the preparation of symmetrical disulfides in high yields and under mild conditions. [Supplemental materials are available for this article.

A green disulfide synthesis method
-
Paragraph 0034-0036, (2022/01/08)
The present invention discloses a green disulfide synthesis method, belonging to the field of green chemical and organic synthesis technology. Under room temperature, open, neutral conditions, rapid preparation of parent nuclei is alkanes, olefins, aromatic hydrocarbons, oxazole, thiazole, pyrazole, imidazole, etc. and their derivatives of symmetrical disulfide, the catalyst is MBrx(M is Fe2+,Fe3+,Ce3+, etc., x is 2-3), the only oxidant isH2O2. The present invention is reacted by using commercially available and low-cost reagents (e.g., FeBr2,CeBr3 andH2O2,etc.) and common organic solvents, the steps are concise, the operation is convenient, the reaction is rapid, the reaction conditions are mild, the room temperature is open, and no further purification can be obtained pure disulfide, more advantageous than all previous methods, is expected to be in organic synthesis, medicine, Pesticides and electronics and other industries are widely used.
