SYNTHESIS OF AMINATED CYCLOTRIPHOSPHAZENES. SOLVENT EFFECTS ON THE PRODUCT-SELECTIVITY OF THE AMINATION

摘要

We investigated the reaction between hexachlorocyclotriphosphazene ((NPCl2)(3)) and gaseous ammonia in several solvents to find that (NPCl2)(2)(NP(NH2)(2)) was obtained in solvents having low dielectric constant such as toluene and ether, whereas novel compound, (NPCl2)(NP(NH2)(2))(2), was selectively obtained in solvents having high dielectric constant such as acetonitrile.
