The synthesis and characterization of some schiff base derivates of 2,2-bis(2-formylphenoxy)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene

In this study, hexachlorocylotriphosphazene(1) was reacted with biphenyl-2,2?-diol. From this reaction, 2,2-dichloro-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(2) was obtained. Since hexachlorocylotriphosphazene is sensitive to air and moisture, experimental studies were carried out at without air and moisture in argon atmosphere. 2,2-Bis(2-formilphenoxy)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(3) was synthesized from the reaction of (2) with 2-hydroxybenzaldehyde Schiff base containing 2,2-Bis(2-formilphenoxy)(4-methoxybenzylimin)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(4), 2,2-Bis(2-formilphenoxy)(2-chlorobenzylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(5), 2,2-Bis(2-formilphenoxy)(4-chlorobenzylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(6), 2,2-Bis(2-formilphenoxy)(R-(+)-1-(2-naphthylethylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(7), 2,2-Bis(2-formilphenoxy)(2-hydroxyphenylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(8), 2,2-Bis(2-formilphenoxy)(2-hydroxyphenylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(9), 2,2-Bis(2-formilphenoxy)(4-nitrilephenylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(10), 2,2-Bis(2-formilphenoxy)(2-phenylphenylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(11), 2,2-Bis(2-formilphenoxy)(2-hydroxy-4chlorophenylimine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene (12) and 2,2-Bis(2-formilphenoxy)(pyridine-2-imine)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene(13) were synthesized by the reaction of 2,2-Bis(2-formilphenoxy)-4,4,6,6,-bis[spiro(2?,2??-dioxy-1?,1??-bifenilyl)]cyclotriphosphazene (3) with 4-methoxy benzylamine, 2-chlorobenzylamine, 4-chlorobenzylamine, 2-naphthylethylamine, 2-hydroxyphenylamine, 2-hydroxyphenylamine, 4-nitrilephenylamine, 2-phenylphenylamine, 2-hydroxy-4chlorophenylamine and pyridine-2-amine, 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 the reaction of (3) with R-(-)-1-cyclohexylethanamine and 4-methylebenylamine.KEYWORDS: Hexachlorocyclotriphosphazene, phosphazene, schiff base, schiff base and phosphazenes
