Reaction Conditions:

with acetic acid at 120 - 135; for 8 h;

Steps:

2.2
2 g of dioctylphosphine oxide (0.007mol) is added into 20 ml of acetic acid, after heating at 120 ° C, slowly added the drops of 2.2 (0.020 mol) g of octane, continue heating at 135 ° C for 8 hours, 31PNMR detection reaction end point, after the reaction is completed, add chloroform and distilled water, remove acetic acid, the chloroform is distilled off under reduced pressure (400 Pa, 35 ° C), Vacuum drying (120 Pa, 25 ° C) and obtained white solid, 2.2 g (0.0057 mol). Yield is 81.4%.
