Propanephosphonic acid anhydride - Wikipedia Propanephosphonic acid anhydride (PPAA, T3P) is an anhydride of propane phosphonic acid Its structure is a cyclic trimer, with a phosphorus–oxygen core and propyl groups and additional oxygens attached [1]
Propylphosphonic anhydride = 50wt. ethyl acetate 68957-94-8 Propylphosphonic anhydride (T3P) is a reactive n -propyl phosphonic acid cyclic anhydride [1] It is a mild and low toxic coupling agent used in peptide synthesis [2] T3P also acts as a promoter and water scavenger in the Friedländer annulation reaction [3]
Propane-phosphonic Acid Anhydride – T3P® | Curia T3P® (propanephosphonic acid anhydride) is a cutting-edge reagent for condensation reactions Trusted by leading pharmaceutical companies, T3P ® simplifies amide and peptide bond formations while supporting a range of transformations like nitrile formation, alcohol oxidation, and heterocycle synthesis
Propylphosphonic anhydride (T3P - ScienceDirect Propylphosphonic anhydride (T3P ®) has been demonstrated to be an efficient and mild reagent for the one-pot synthesis of 1,2,4-oxadiazoles, 1,3,4-oxadiazoles, and 1,3,4-thiadiazoles from carboxylic acids
pH-Dependent Degradation of T3P-Related Byproducts This communication discusses the isolation and characterization of a T3P degradation byproduct and removal of the water-soluble byproduct by washing or further degradation at low pH A second example demonstrates the degradation of a T3P-related phosphonic ester at low pH
