Abstract

Alumina-supported ammonium acetate under microwave irradiation was found to be an efficient reagent for the preparation of phosphorodithioates from phosphorus pentasulfide under solvent-free condition. A simple, efficient, and new method has been developed for the synthesis of thiiranes from epoxides through a one-pot reaction of epoxides with the mixture of phosphorus pentasulfide in the presence of ammonium acetate and acidic alumina under reflux in EtOH or solvent-free conditions under microwave irradiation. These methods are easy, rapid, and good-yielding reactions for the synthesis of phosphorodithioates and thiiranes.
