Wittig Reaction of Quaternary Phosphonium Salts Containing Macromolecular Ligands Functionalized with Aldehyde Groups

摘要

The Wittig reaction is amongst the most popular methods for regiospecific introduction of carbon-carbon double bonds in organic synthesis.The paper deals with the synthesis of copolymers functionalized with olefin groups by Wittig type polymer-analogous reactions in phase transfer catalysis.The copolymer bond aldehyde was reacted with phosphonium salts to give olefin groups grafted on macromolecular support.
