peroxidase (GPx) enzymes for oxidation of thiols by oxygen and hydrogenperoxide, respectively, into disulfides has been presented. The developed catalyst oxidizes an array of organothiols into respective disulfides in practical yields by using aerial O2 to avoid any reagents/additives, base, and light source. The synthesized diselenide also catalyzes the reduction of hydrogenperoxide into water by following

Abstract In the present study, the reaction of thiols with alkyl sulfonyl halides was carried out in a nitrogenous base to compare the reactivity of ‐SH with that of ‐OH, which, however, led to the formation of disulfides. The reaction achieved as a result offers the use of an inexpensive reagent, quantitative yields of the product, and simplicity for the formation of the S‐S bond.
An inexpensive combination of common laboratory reagents, dimethyl sulfoxide (DMSO) and chromatographic neutral alumina, gives an efficient, selective, and high-yielding oxidation of aromatic, aliphatic and alicyclic thiols to the corresponding disulfides in excellent yields under relatively mild conditions.
