for the iron-catalyzed preparation of selenoesters by the reaction of diselenides with acylchlorides or acid anhydrides has been developed. In the presence of magnesium dust, iron catalyzes the cleavage of the Se-Se bonds of the diselenides; the subsequent smooth reaction with acylchlorides or acid anhydrides generates the corresponding selenoesters in good yields. The reaction could be carried out
