Usage

General Description

3,3',5,5'-Tetrachlorodiphenyl disulfide is a synthetic organic compound that belongs to the class of chemicals known as dichlorobenzenes. 3,3',5,5'-TETRACHLORODIPHENYL DISULFIDE is characterized by the presence of two benzene rings, each of which is substituted with two chlorine atoms. It also contains a disulfide bond, a functional group composed of two sulfur atoms. Due to its chemical structure, it exhibits various physical and chemical properties, including high thermal stability and resistance to oxidative degradation. Unlike other halogenated organic compounds, 3,3',5,5'-tetrachlorodiphenyl disulfide is less persistent in the environment owing to the presence of its disulfide bond, making it relatively easier to degrade and remove. This chemical is not widely used and its toxicity and potential ecological effects are not well-studied.

Green Aerobic Oxidation of Thiols to Disulfides by Flavin-Iodine Coupled Organocatalysis

Coupled catalysis using a riboflavin-derived organocatalyst and molecular iodine successfully promoted the aerobic oxidation of thiols to disulfides under metal-free mild conditions. The activation of molecular oxygen occurred smoothly at room temperature through the transfer of electrons from the iodine catalyst to the biomimetic flavin catalyst, forming the basis for a green oxidative synthesis of disulfides from thiols.

Synthesis of aryl perfluoroalkyl sulfides from aromatic disulfides

Thermolysis of xenon(II) bis(perfluoroalkanecarboxylates) in the presence of diaryl disulfides occurs through the S-S bond cleavage to form dihalo-, halonitro-, and halodinitrophenyl perfluoroalkyl sulfides. The latter type of compounds was obtained for the first time. The main side process is the perfluoroalkylation of the aromatic ring.

Synthesis of carbonates and related compounds from carbon dioxide via methanesulfonyl carbonates

Carbonate anions resulting from reaction of primary or secondary alcohols with carbon dioxide, when added to methanesulfonic anhydride in cooled acetonitrile solution, yield methanesulfonyl carbonates, a new class of synthetic intermediate. Base-mediated reaction of the methanesulfonyl carbonates with alcohols, thiols, and amines yields carbonates, thiocarbonates, and carbamates, respectively. Overall yields for the three steps vary from 19% to 42%.
