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.

An umpolung approach for the synthesis of unsymmetrical disulfides via sulfenium ion is reported. In situ generated electrophilic sulfenium ion from electron-rich thiols reacted with second thiols to yield unsymmetrical disulfides. Using an iodine catalyst and 4-dimethylaminopyridine (DMAP)/water as promoter, the target syntheses were achieved in one pot under aerobic condition.
Laccase-catalyzed in situ generation and regeneration of N-phenyltriazolinedione for the aerobic oxidative homo-coupling of thiols to disulfides

The first report on aerobic in situ generation and regeneration of N-phenyltriazolinedione, a valuable oxidizing agent, from a catalytic amount of N-phenyl urazole in the presence of a laccase enzyme is presented. The application of a 4-phenyl urazole/Laccase/O2 as a new cooperative catalytic oxidation system is reported for a transition-metal-free and halogen free oxidative homo-coupling reaction of structurally diverse thiols to their corresponding disulfides with good to excellent yields in a phosphate buffer solution under mild reaction conditions.
