Anwendungen & Verwendung

Verwenden

2-Chloro-4H-1,3,2-benzodioxaphosphorin-4-one is a reagent used in phosphorylation and phosphitylation of alcohols and in the formation of H-phosphonates. It is also reactive cyclic phosphitylating reagent involved in fast coupling rates and hydrolytic cleavage more readily compare to that of a acyclic analog.
