- As acid activating agent for the direct synthesis of acid azides from carboxylic acids.
- One-pot synthesis of coumarins.
- Microwave-mediated synthesis of carbocyclic and heterocyclic fused quinolones.
- One-pot synthesis of 1,2,4-oxadiazoles, 1,3,4-oxadiazoles, and 1,3,4-thiadiazoles from carboxylic acids.
- Activation of the carboxyl group for hydroxyamidation and peptide coupling and in the one-pot conversion of carboxylic acids into hydroxamic acids.
| | General Description | Propylphosphonic anhydride (T3P) is a reactive n-propyl phosphonic acid cyclic anhydride. It is a mild and low toxic coupling agent used in peptide synthesis. T3P also acts as a promoter and water scavenger in the Friedl?nder annulation reaction. It participates in the conversion of carboxylic acids and amides into nitriles, formation of Weinreb amides, ester synthesis, dehydrations, oxidation of alcohols, isonitrile synthesis, synthesis of alkenes from alcohols and C-C coupling reactions. T3P delivers outstanding advantages over traditional reagents, such as broad functional group tolerance, low epimerization, and water-soluble by-products and hence gives high purity and yield of the product. | | Flammability and Explosibility | Notclassified |
