PRODUCTION OF ORGANOPHOSPHAZENE

摘要

PURPOSE:To obtain an N-silyl-organophosphazene compound useful as a raw material and intermediate for the synthesis of polyorganophosphazene in one step and high yield by reacting an organosilylazide compound with a phosphite compound in a polar solvent. CONSTITUTION:The objective compound of formula III can be produced by reacting an organosilylazide compound of formula I [R<1> to R<3> are (substituted) univalent hydrocarbon group] (preferably trimethylsilylazide) with a phosphite compound of formula II [R<4> to R<6> are (substituted) univalent aromatic group or univalent aromatic heterocyclic group] (e.g. triphenyl phosphite) in a polar solvent (preferably DMF, etc.) at room temperature to 200 deg.C for 30min to 10hr. The amount of the compound of formula II is preferably 0.2-10mol per 1mol of the compound of formula I.
