  The nucleophilic substitution reaction of hexachlorocyclotriphosphazene (N3 3 P3 3 Cl6 6 , trimer) (1) with 4-hydroxy-1-naphthaldehyde (2) has been investigated for the first time. 4′ ′ -Oxy-1′ ′ -naphthaldehyde substituted mono- (3), bis- (4), and tris- (5) cyclotriphosphazenes were obtained from the nucleophilic substitution of compound 1 with 2 in a 1:2 molar ratio in the presence of Cs2 2 CO3 3 in acetone at reflux. The pentakis-(6) and hexakis-substituted (7) cyclotriphosphazenes were prepared from the reaction of 1 with 2 in a 1:7 molar ratio using K2 2 CO3 3 as a proton abstractor in tetrahydrofuran at room temperature. The structures of the new compounds (3-7) were determined by elemental analysis, FT-IR, and mass and nuclear magnetic resonance (1 1 H and 31 31 P) spectroscopies.
