Abstract

A rapid and efficient method for the large-scale synthesis of symmetrical disulfides and diselenides is developed involving oxidative coupling of corresponding thiols and selenols using bipyridinium hydrobromide perbromide (BPHP).

ACKNOWLEDGMENT

The authors are grateful to the Razi University Research Council and Kermanshah Refinery Company for the support of this work and Mr. M. Irandoost for running the NMR spectra.
