The derivates synthesis and characterization of some schiff base of hexa(2-formyl?5-methoxyphenoxy)cyclotriphosphazene

Hexa(2-formyl-5-methoxyphenoxy)cyclotriphosphazene(2) was obtained from the reaction of hexachlorocyclotriphosphazene(1) with 2-hydroxy-4-methoxybenzaldehyde in presence of K2CO3 at room temperature in THF under argon atmosphere. Schiff base containing 2,4,6-tris[2-(2-iminophenol)-5-methoxyphenoxy]-2,4,6-tris(2-formyl-5-methoxyphenoxy)cyclotriphosphazene(3), 2,4,6-tris[2-(4-iminobenzoicacid)-5-methoxyphenoxy]-2,4,6-tris(2-formyl-5-methoxyphenoxy) cyclotriphosphazene(4), 2,4-bis[2-(2-imino-4-methyl-1,3-thiazole)-5-methoxyphenoxy]-2,4,6,6-tetra(2-formyl-5-methoxyphenoxy)cyclotriphosphazene(5), hexa[2-[(4-iminobenzamide)-5-methoxyphenoxy]cyclotriphosphazene(6), 2,4,6-tris[2-(5-imino-1,3,4-thiazole-2-thiol)-5-methoxyphenoxy]-2,4,6-tris(2-formyl-5-methoxyphenoxy)cyclotriphosphazene(7), 2-[2-(2-iminobenzothiazole)-5-methoxyphenoxy]-2,4,4,6,6-penta(2-formyl-5-methoxyphenoxy) cyclotriphosphazene(8) hexa[2-[(4-iminophenol)-5-methoxyphenoxy]cyclotriphosphazene(9) and 2,4,6-tris[2-(4-iminoasetophenon)-5-methoxyphenoxy]-2,4,6-tris(2-formyl-5-methoxyphenoxy) cyclotriphosphazene were synthesized by the reaction of hexa[(2-formyl-5-methoxy)phenoxy]cyclotriphosphazene(2) with 2-aminophenol, 4-aminobenzoicacid, 2-amino-5-methyl-1,3-thiazole, 4-aminobenzamide, 5-amino-1,3,4-thiazole-2-thiol, 2-aminobenzothiazole, 4-iminophenol and 4-iminoasetophenon respectively. The structures of the compounds were characterized by IR, 1H, 13C and 31P NMR spectroscopy and elemental analysis. Schiff base compounds could not be obtained from hexa[(2-formyl-5-methoxy)phenoxy]cyclotriphosphazene(2) with 2-amino-4-chlorophenol and 2-aminobenzimidazole.KEY WORDS: Phosphazenes, cyclotriphosphazenes, hexachlorocyclotriphsophazene, schiff base, schiff base and phosphazenes.
