The reactions of elemental phosphorus, arsenic and antimony with sodium metal in liquid ammonia form “M−1“ species that react with haloarenes under irradiation to form symmetrical triaryl derivatives of these metals by the SRN1 mechanism in fair to good yields. Further reaction with sodium metal gives a derivative nucleophile (diarylphosphide and diarylarsenide ions) that reacts with another haloarene
