Usage

General Description

Dimethyl 2,2'-dithiobisbenzoate is a chemical compound that is used as a polymerization inhibitor in various industrial processes, particularly in the production of synthetic rubbers and plastics. It is known for its ability to effectively prevent the unwanted polymerization or solidification of certain monomers, thus ensuring the stability and flowability of the materials during production and storage. dimethyl 2,2'-dithiobisbenzoate is also used as a stabilizer in the formulation of adhesives, coatings, and sealants, where it helps to maintain the integrity and performance of the end products. Additionally, dimethyl 2,2'-dithiobisbenzoate has been found to exhibit antioxidant properties, making it valuable for extending the shelf life of certain reactive substances. However, it is important to handle this chemical with care, as it may pose risks to human health and the environment if not used and disposed of properly.

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.

A novel pathway for the thermolysis of N-nitrosoanthranilates using flash vacuum pyrolysis leading to 7-aminophthalides

Flash vacuum pyrolysis of methyl N-methyl-N-nitrosoanthranilate leads to elimination of nitric oxide and disproportionation of the formed N-radical to 7-(methylamino)phthalide and methyl N-methylanthranilate. This transformation was found to be a convenient, solvent-free method for the preparation of 7-(methylamino)phthalides. An alternative route through pyrolysis of N-benzyl-N-methyl anthranilates was also investigated. This journal is

Synthesis of aryl cyclopropyl sulfides through copper-promoted S-cyclopropylation of thiophenols using cyclopropylboronic acid

The copper-promoted S-cyclopropylation of thiophenols using cyclopropylboronic acid is reported. The procedure operates under simple conditions to afford the corresponding aryl cyclopropyl sulfides in moderate to excellent yields. The reaction tolerates substitution in ortho-, meta- and para-substitution as well as electron-donating and electron-withdrawing groups. The S-cyclopropylation of a thiophenol was also accomplished using potassium cyclopropyl trifluoroborate.
