A green disulfide synthesis method

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.

TEMPO visible light photocatalysis: The selective aerobic oxidation of thiols to disulfides

TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) is well-established in orangocatalysis that usually work in synergy with transition-metal catalysis or semiconductor photocatalysis. Here, TEMPO was turned into a visible light photocatalyst to conduct the selective aerobic oxidation of thiols into disulfides. With O2 as an oxidant, a mild and efficient protocol for the selective oxidation of thiols into disulfides including symmetrical and unsymmetrical ones with 5 molpercent of TEPMO as a photocatalyst was developed at room temperature under the irradiation of 460 nm blue LEDs. It was found that a complex formed between TEMPO and thiols underpinned the visible light activity and disulfides were obtained in very high isolated yields. This work suggests that TEMPO takes diverse roles in for photocatalytic selective oxidative transformations with O2 as the oxidant.
