Abstract
The Wittig reaction between hexakis(4-formylphenoxy) cyclophosphazene [NP(O-C 6H 4- p-CHO) 2] 3 ( 1) and several stabilized phosphonium ylides leads to the preparation of double bond-containing cyclophosphazenes. All the characterization data obtained for the synthesized compounds indicated that the cyclophosphazene ring is not involved in this reaction, the only reactive functions being the aldehydic groups in the side substituents of 1. These products proved to be promising materials in further functionalization studies and may open interesting perspectives in the case of the corresponding phosphazene high polymers.
