Synthesis

Phosphonium salt (2.2 mmol) was added to a cooled solution (- 78 ??C) of Et3N (4.44 g, 44 mmol) in di-n-butyl ether (20 mL). The reaction mixture was stirred at -78 ??C for 5 h and then allowed to warm gradually to r.t. The solvent was removed under vacuum and the residue was dissolved in degassed EtOH (5 mL). After stirring for 15 min, the solid was filtered off and dried to yield the desired phosphine, which can be further purified by crystallization from EtOH. Butyldi-1-adamantylphosphine, yield 90%.
