Abstract

2,2-Dichloro-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)]cyclotriphosphazene was synthesised from the reaction of hexachlorocyclotriphosphazene with biphenyl-2,2′-diol. 2,2-Bis(4-formylphenoxy)-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)]cyclotriphosphazene was obtained from the reaction of 2,2-dichloro-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)] cyclotriphosphazene with 4-hydroxybenzaldehyde. 2,2-Bis[4-(4-quinazolinone)phenoxy]-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)]cyclotriphosphazene was synthesised from the reaction of 2,2-bis(4-formylphenoxy)-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)]cyclotriphosphazene with anthranilamide in N,N-dimethylformamide. The novel cyclophosphazene derivatives were synthesised under mild conditions from the reaction of 2,2-bis[4-(4-quinazolinone)phenoxy]-4,4,6,6-bis[spiro(2′,2″-dioxy-1′,1″-biphenylyl)]cyclotriphosphazene with 4-chlorobenzenemethanethiol, p-thiocresol, 4-aminothiophenol, and 4-chlorothiophenol in the presence of p-toluenesulfonyl chloride via C-OH bond activation under mild conditions. All products were generally obtained in high yields. Their structures were characterised by HRMS, IR and 1H, 13C spectroscopy.
