In the drybox lithium indenide (8.00 g, 65.52 mmol) dissolved in 50 mL of THF was added within 15 minutes to a 180 mL ether solution of diphenylchlorophosphine (14.46 g, 65.52 mmol) (diphenylchlorophosphine was distilled before use (97° C. @ 0.4 torr)). After stirring overnight, LiCl was separated by filtration giving a yellow solution. Solvent was removed under vacuum leaving an off-white solid. This solid was triturated with 40 mL of hexane. Hexane was removed by decanting and the solid was dried under reduced pressure to give 16.43 g of off-white solid. Yield 84 percent.
