Mild and Highly Efficient Preparation of Symmetrical Disulfides and Diselenides
Using Bipyridinum Hydrobromide Perbromide as a New Oxidative Reagent. —
A rapid and efficient method for the preparation of symmetrical disulfides and diselenides is given. The method is useable for large scale syntheses too. In the presence of
a second thiol no cross-coupling products are observed. Groups sensitive to oxidation
like anilines or aldehydes are stable and remain intact. — (JOSHAGHANI*, M.;
