Applicazioni

1-Propylphosphonic acid cyclic anhydride is used as a reagent for amide/peptide bond formation. It is utilized for condensation reactions and alcohol oxidations. It is also used to promote the synthesis of hydroxamic acids from carboxylic acids. Further, it is employed as an efficient promoter for the Lossen rearrangement to synthesis urea and carbamate derivatives.

Note

Moisture sensitive. Incompatible with strong oxidizing agents.
