Description and Uses
Propylphosphonic anhydride may be used in the following studies:
- As coupling agent for the synthesis of bispyridine-based ligands, which are used as bridging linkers in multinuclear platinum anticancer drugs.
- Microwave-assissted Fischer indolization of arylhydrazines.
- 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.
