Synthesis of 2-Aryloxy-2,4,4,6,6-pentachlorocyclotriphosphazenes (N3P3Cl5(OAr)): Monoaryloxylatioin of Hexachlorocyclotriphosphazene (N3P3Cl6) and Mass Spectra of Chlorocyclotriphosphazene Derivatives. Difference between EI vs. ESI Methods

Hexachlorocyclotriphosphazene (HCCP, N3P3Cl6) was treated with Li aryloxide in THF at -40 ºC to give monoaryloxypentachlorocyclotriphosphazene (N3P3Cl5(ArO)) selectively. N3P3Cl5(ArO) did not give further aryloxylated products N3P3Cl6-n(ArO)n (n ≥ 2) under the same reaction conditions. In mass spectra (MS) of N3P3Cl5(ArO), [N3P3Cl5(ArO)]+ were detected by EI method, whereas partially hydrated products [N3P3Cl4(ArO)(O-)] were detected instead of [N3P3Cl5(ArO)]+ by ESI method.
