The reactions of elemental phosphorus, arsenic and antimony with sodium metal in liquid ammonia form "M^-3" species that react with haloarenes under irradiation to form symmetrical triaryl derivatives of these metals by the S_RN1 mechanism in fair to good yields.Further reaction with sodium metal gives a derivative nucleophile (diarylphosphide and diarylarsenide ions) that reacts with another haloarene under irradiation to form unsymmetrical phosphines and arsines.
