A new reaction route has been developed for the synthesis of a hitherto inaccessible series of 1,1-dialkyltetrachlorocyclotriphosphazenes, N3P3Cl4RR’ (III), where R = CH3, C2H5, n-C3H7, n-C4H9, i-C4H9, t-C4H9, or allyl and R’ = CH3, C2H5, n-C3H7, n-C4H9, or allyl. The high-yield route involves the interaction of hexachlorocyclotriphosphazene, (NPCl2)3, with alkyl Grignard reagents in the presence of [n-Bu3PCuI]4, followed by treatment with alkyl halides. The structural characterization of these compounds by NMR and mass spectrometric techniques is discussed, together with the reaction mechanism.
