Thiol oxidation to disulfides is an area of great importance in organic synthesis, both for synthetic and biological purposes. Herein, we report a mild, inexpensive and green photochemical approach for the synthesis of both symmetrical and non-symmetrical disulfides, using metal-free and environmentally friendly conditions. Utilizing phenylglyoxylic acid as the photoinitiator, common household bulbs
A novel TentaGel resin supported platinum(IV) complex named TentaGel-Pt(IV) was synthesized and characterized by SEM, XPS, ICP-MS and UV-vis spectrophotometry. The formation of intramolecular disulfides in eleven dithiol-containing peptides of variable lengths using TentaGel-Pt(IV) was investigated at room temperature. The disulfide-containing peptides were formed in excellent oxidation yields and

This invention discloses a method for producing polyarylene thioether by the catalytic oxidative coupling polymerization of at least one compound selected from the group consisting of diaryl disulfides of general formula (I) and thiophenols of general formula (11), wherein R1 to R12 are each as defined in the specification, by using oxygen in the presence of an acid. According to the above method, the reaction proceeds under very mild conditions; the procedure can be simplified; and the starting material and catalyst an available at extremely low cost. Thus, this method is advantageous industrially.
