A new reduction system: combination of sodium sulfide (sodium hydrosulfide) with phase transfer agent in a two-phase mixture. Reductive debromination ofvic-dibromides to olefins

Abstract A wide variety of vic -dibromides are debrominated to the corresponding olefins in good to excellent yields are aqueous sodium sulfide or sodium hydrosulfide using tricotylmethylammon chloride as the phase transfer agent in a two-phase mixture.
