Descripción

Descripción general

Triphenylphosphine, polymer-bound is polystyrene crosslinked with divinylbenzene, widely used in many organic syntheses such as peptide synthesis, heterocycle synthesis, esterification, and total synthesis. It can be easily removed from the reaction products by simple filtration.

Aplicación

Triphenylphosphine, polymer-bound is used as a polymer support to synthesize dipeptides, olefins, aryl-alkyl ethers, and in the esterification of alkylphosphonic acids. It acts as a Lewis acid, and dehydrating agent when complexed with halogen, hence useful in the acetonation of sugars.
