[Na{P(Si i Pr3)2}]. A three neck 500 mL round bottom Schlenk was charged with red phosphorus (3.100 g, 100.0 mmol) and dried under vacuum for ca. 12 hours. DME (ca. 250 mL) and naphthalene (3.00 g, 23.4 mmol) were added. Chunks of Na washed in hexane (6.897 g, 300.0 mmol, 3 eq.) were added in small portions over the space of 30 mins. The reaction mixture was stirred at reflux (100 ℃) for 16 hours, and became dark green in color.
