実験手順

Bis(diisopropylamino)chlorophosphine was synthesized by reacting phosphorous trichloride and diisopropylamine in toluene. Fifty ml of the resulting bis(diisopropylamino)phosphine was placed in a 250 ml flask and 3.01 ml of ethanol added slowly over a two minute period and the reaction allowed to proceed for several days. After filtering the mixture and removing the solvent, the structure of the bis(diisopropylamino)ethylphosphite ester reagent was analyzed by 31P and 1H NMR (31P NMR in CD3CN 125.9 ppm).
