2-Chloro-1,3,2-dioxaphospholane Chemical Properties, Uses, Production

Chemical Properties

Clear Colourless Oil

Uses

Highly reactive cyclic phosphitylating reagent which provides fast coupling rates, and hydrolytic cleavage occurs more readily than with acyclic analogs

Uses

Ethylene chlorophosphite acts as a phosphitylating agent involved in the preparation of phosphocholine and spirophosphoranes. For example, it is used in the phosphorylation of p-tert-butyl(thia)calixarenes.
