반응 단계
Dicyclohexyl phosphine (40 g, 0.2 mole) was reacted with ethylene dibromide (18 g, 0.1 mole) for 2 hours at 90°-100° C. to form ethylenebis(dicyclohexylphosphine). The phosphine compound was then oxidized with 25 g of 30% hydrogen peroxide to give the phosphine oxide. The crude product was recrystallized from isopropanol/water to give 20 grams of the subject compound, m.p. 199°-201° C.
