TETRAETHYL PYROPHOSPHITE Chemical Properties,Usage,Production

Chemical Properties

clear colorless liquid

Uses

Tetraethyl Pyrophosphite is used as a reagent in the preparation of peptides and in the phosphonylation of carbonyl compounds.

Uses

The product can be used as a reagent for peptide synthesis.

Application

Tetraethyl pyrophosphite can be used in peptide synthesis; phosphonylation of ketones, aldehydes, and perfluoroalkyl iodides.

Preparation

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.
