実験手順
Bis-(N,N-Diisopropylamino) chlorophosphine, 10 grams (37 mmols), was dissolved in 500 ml of anhydrous acetonitrile. Phosphorus trichloride, 5.16 grams (37 mmols), was added to the solution and the reaction was allowed to stir over-night at room temperature. The reaction was assayed for completion by 31P NMR of an aliquot of the reaction using an external lock. Complete conversion of the starting material at δ 134 ppm to the product at δ 165 ppm was observed. The solvent was evaporated from the reaction mixture on a rotary evaporator and the resulting oil distilled under vacuum yielding 5.7 grams of product (81% yield).
