使用Tetraethyl Pyrophosphite is used as a reagent in the preparation of peptides and in the phosphonylation of carbonyl compounds.
製造方法The most convenient method involves the reaction of diethyl phosphite with diethyl phosphorochloridite. Diethyl phosphorochloridite (223 g) is added rapidly to a solution of diethyl phosphite (138 g) and triethylamine (101 g) in benzene (200 ml). The mixture is filtered and the benzene removed by distillation at reduced pressure. The product is isolated by further distillation at reduced pressure (79-81 °C/0.15 mmHg) in 41% yield.
