Abstract
The stoichiometric oxidation of thiols to their corresponding homodisulfides by arylglyoxals has been described. The process has several advantages: high yields, short reaction times, simple experimental and work-up procedures.

Notes
It has been pointed out that, nevertheless, H2O2 is not a very good reagent for this reaction, since it gives sulfonic acids as well as disulfides.
